• WIfi Problems Ubuntu 13.10

  - by user289429

  i've been searching the forums for two days now but none of the answers seems to work for me. I have an acer extensa 5630 which has an Intel WIfi 5100. But even when i am right next to my router i cannot detect the wireless network. The weird thing is, that when i create a hotspot from my mobile phone it automatically detects it and connects to it.I think i do have the correct drivers installed. Thanks

• Ubuntu 13.10 - Wifi not re-connecting after suspend

  - by Matthew

  I upgraded the other day from Ubuntu 13.04 to 13.10 on my ZaReason laptop, and the WiFi doesn't reconnect after suspend. In 13.04, pressing Fn+F2 turned network connections back on after suspend. The 'soft' wireless hardware switch. But in 13.10, that doesn't work, and trying to enable networking in the networking menu doesn't work either. So I have to restart every time. Any suggestions to make it work?

• Is there a way to get my NETGEAR N900 to work with ubuntu?

  - by user208088

  I'm using a NETGEAR N900 USB Wireless Adapter to pick up our home network connection while running Windows 7. I have Ubuntu 12.04.3 running on a second hard drive in my computer that is not compatible with my adapter. I'm not very familiar with how to work around in Ubuntu yet and this is the only thing keeping me from using it. I've seen this asked before but the instructions were very confusing to me! Help is appreciated

• WiFi on Ubuntu 12.04 custom: downloading unbearably slow

  - by Mark

  iwconfig reports 11 Mbps, yet I've seen as low as <1 KBps. This is the latest in my laundry list of Ubuntu problems in a dual-boot machine (cyberpowerpc custom, intel i7-3820, nvidia gtx 570). I received it two days ago, Windows 7 running fine, still having problems with Ubuntu. The browsing is intermittent but unacceptable. e.g. I could get to this site last night but I couldn't post this question. The downloading is unbearably slow, I can't download anything or install any packages because the speed is so slow. e.g. I am trying to install vim which is inexplicably missing from my 12.04 install (add another one to the problems list) and my download speed reported in the terminal was 241 B/s. Yes, bytes. iwconfig reports 11 Mbps, which further adds to the confusion. User@ubuntu:~$ iwconfig lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"linksys" Mode:Managed Frequency:2.437 GHz Access Point: 00:18:39:76:2C:A1 Bit Rate=11 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:54 Invalid misc:18 Missed beacon:0 eth0 no wireless extensions. Any ideas? I see this is a problem a lot of people, but none of the on line solutions have worked for me so far. e.g. one site recommends editing the ath9k.conf file in /etc/modprobe.d, yet this file isn't even in the folder: User@ubuntu:/$ cd etc/modprobe.d User@ubuntu:/etc/modprobe.d$ ls alsa-base.conf blacklist-oss.conf blacklist-ath_pci.conf blacklist-rare-network.conf blacklist.conf blacklist-watchdog.conf blacklist-firewire.conf dkms.conf blacklist-framebuffer.conf nvidia-current_hybrid.conf blacklist-modem.conf nvidia-graphics-drivers.conf I think the nvidia gpu might be mucking things up. I had the "blinking cursor" problem when installing in the first place, and then I had the monitor out of range problem as well. I have my faithful Asus laptop, which is running Ubuntu 12.04 just fine. The only difference is executing host -t SOA local in the terminal gives User@ubuntu:~$ host -t SOA local local has SOA record local. nobody.localhost. 42 86400 43200 604800 10800 in my new machine, and the command reports Host local. not found in the laptop. Help would be most welcome, as I am in danger of reverting back to Windows. I'm seriously considering it. Sorry for the length, trying to show my effort in resolving the issue and include terminal snippets that might be helpful.

• DFS share Access denied for some time after workstation is booted.

  - by Jonathan

  I have 2 Win server 2008 servers acting as domain controllers and Dns servers doing DFS. All my workstations are windows xp sp3. I have a DFS share drive mapped at login via login script. After the pc is booted I get an access denied message when trying to access the mapped drive. If i go to the file share on one of the servers i can get to it fine. After about 10 minutes i can try to access the mapped drive again and it works fine. I am not sure if it is some delay happening in dfs name resolution or a gpo issue.

• internet access options in remote area? (read: no comcast,qwest, etc)

  - by freedrull

  Currently I am living in a fairly "remote" area, in the countryside, and cable internet access through the typical companies like comcast and qwest is just not available here. I've been trying to research other options for fast internet access. There are some small cable companies but they currently do not offer broadband access here. I thought about maybe buying a 3g phone with a data plan and doing some sort of tethering, or perhaps getting an android phone and using it as a wireless AP. This would of course depend on 3g being available here. The only other thing I can think of is some sort of satellite internet service, or doing something crazy like adapting wifi over am radio. Anyone have any ideas, at all, short of moving somewhere else?

• Router's ssid changes from infrastructure to ad-hoc

  - by waldo

  For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop. Details: - D-Link DSL-2740B router set to WPA2-PSK (Personal) - Enable Wireless : Yes - Wireless Network Name (SSID) : ###### - Country : Australia - Wireless Channel : 1 - 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b - Channel Width : Auto 20/40 MHz - Transmission Rate : Best (automatic) - Hide Wireless Network : No - Group Key Update Interval : 0 (seconds)

• How to disable internet access at night on the router?

  - by izb

  I have an internet connection that I'd like to be enabled only during the day. With multiple household internet devices, this would need to be something disabled at the level of the router. I don't believe the router offers this sort of functionality, but I'm reasonably familiar with setting up web servers and the like, and I'm wondering if I can set up some sort of proxy server on the internet that the router must go through and have that proxy only active at certain times of day. It's a bit vague I know, but is something like this even possible? If not, are there other solutions to the problem?

• Why does this work: Windows same local admin username and password, able to access other computer?

  - by Ankush

  I've two machines MachineA and MachineB. Both have two local accounts which have same username . Both accounts are local admin on those machines. If they have same password, I'm able to access \\MachineA\C$ from MachineB. But if I change any one password above doesn't work. And it prompts for username and password. Now if I provide MachineA\username and password, it then connects. Why isn't there a prompt for password when passwords are same? I expected passwords to be hashed with random salt, how does windows know passwords are same and authorize access? These machines are running Windows Server 2008 R2. PS. I've created following reg key to enable drive access HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\LocalAccountTokenFilterPolicy to 1

• Ldap access lists users even if user has no rights...

  - by Patkos Csaba

  I am trying to set up a more complex Active Directory structure for some testing purposes. What I did so far: set up 2 windows (one 2008 and one 2003) to control the same domain set up an Organizational Unit (ou): Developers set up 2 child OUs: "one" and "two" each OU has it's admin: adminOne and adminTwo I denied all access to OU "two" by removing on the Security tab all the groups I don't want to access it. now, when I log in as adminOne and I try to click on OU "two" it says I don't have permissions to see the users and properties of "two" - this is perfect, it's what I want Here comes my problem: I do a LDAP query with the adminOne user on the "Developers" What I expect to happen: I expect to retrieve the users from Developer - One I expect to NOT be able to retrieve the users from Developers - Two What actually happens: ldap shows all the users, both from Developers - One and Developers - Two, even if the user should not have permissions to Developers - Two And now my question: is there any specific settings on Windows 2003 or 2008 Active Directory servers which allow or deny access over LDAP? I could not find any.

• Can I use an apple airport express as a wired bridge?

  - by Chris

  I have a wireless network using an Apple Airport extreme. That device is set up in my office and hooked up to the cable modem. I have a TV in another room which can accept a wired internet connection (not wireless enabled). Can I use an Apple airport express's ethernet jack to create a wireless to wired bridge? If not what device would I use to do the same thing?

• Bridging networks problems

  - by Eric

  In my setup I have 3 computers and 2 (wireless d-link) routers. Computer1 has ethernet and wireless interfaces ethernet : 192.168.0.x (DHCP) wireless : 192.168.10.254 (static) Computer 2 has ethernet with two ips ethernet1 : 192.168.0.90 (static) ethernet2 : 192.168.10.110 (static) Computer 3 is a particular device with a hardcoded ip that I can't change wireless : 192.168.10.41 (static) Router1 manages internet and DHCP for network 192.168.0.0/24 Router2 is more complicated. I don't use DHCP. I use it to bridge between both networks. Its static ip is 192.168.10.1 Computer1 can ping Computer2. Computer1 can ping Computer3. Computer1 can ping Router1. Computer1 cannot ping Router2. Computer2 cannot ping Computer3. Computer2 can ping Router2. Router1 can ping Router1 Router2 can ping Computer2 Router2 cannot ping Computer1 Router2 cannot ping Computer3 This is very weird. Router2 manages the wireless connection, it should be able to ping its own computers right? My question is obviously : How can I make it so Computer2 can access everything else. This is a traditional case of "it was working before christmas and now it doesn't". The ethernet wiring is as follow : [ Computer1 ]----[ Router1 ]---[ Router2 ]---[ Computer3 ] I am using switch (lan) ports on Router1/2.

• Windows 7/8 can't connect to an N Router

  - by xenoterracide

  I have a router running OpenWRT backfire, with N and A/B/G being broadcast. A linux laptop, and a Mac laptop can see the N network and connect to it (or at least they could last weekend). But there is now a Windows 7 Desktop with a B/G/N wireless card, and a Windows 8 Laptop with a B/G/N wireless card that can't see the N network only the B/G broadcast. The B/G and N have different SSID's and Encryption ( WEP and WPA2 PSK respectively ). The N SSID isn't even visible. Does anyone have any suggestions as to how to troubleshoot further? Or what might be the cause? update wireless info Desktop Dell Wireless 1502 802.11b/g/n Atheros Communications Inc 9.2.0.412

• Network configuration with limited hardware

  - by Pavel

  I have cable internet and I have two PC. One of them has wireless and ethernet, the other pc has ethernet only. Also, I have a dsl modem that has wireless builtin (some common speedstream model). My goal is to connect all of them so that both have internet access. As I understand, I have two options: connect speedstream to the cable and then connect other PC's to speedstream; OR, connect pc with wireless to the cable and then connect the other pc that has ethernet only using ethernet+wireless through speestream. First one seems to be easy, but it doesn't seem to work. What about the other choice? Is it possible to do it?

• How do I turn a Wi-Fi "hotspot" into a local wired network?

  - by Max Schmeling

  Here's the situation: In a remote "office" I have a computer with no network connection, that I need to network with when I'm at this remote office. There is a wireless network where this computer is, but no wireless adapter in the computer. I have a laptop running Windows 7 that can connect to the wireless, and the computer is running Windows Vista. What is the best way to get them both connected? I know I can buy a USB wireless adapter or something for the computer, but is there an easy way to do it with what I've got?

• Is it possible to access internet on smart-phone through usb (no wi-fi) using Laptop as the modem?

  - by Prahlad Yeri

  One of my relatives has a nokia 5235 smartphone. It is good, but the only limitation is - there is no wifi. bluetooth & usb are the only connectivity options. His laptop has an unlimited broadband but no support for bluetooth, so basically usb is the only method by which he can connect the mobile with laptop. Now, he can do a file-transfer between these two devices, but by any chance, is there a way by which we can share the Laptop's internet connection through usb to the smart-phone? So, bascially its like this: Broadband-modem = Laptop =usb= smart-phone -(want to use internet here) Are there any software or utilities available to achieve this ?

• When a new user is created on Centos 6, it takes a while (30 mins) before he can access his group folder

  - by Diepseun

  I created a new user and made it part of a certain group which has full access (777) to a folder. Checked the user in Samba, password the same as his Windows (XP) password, rebooted his desktop but he didn't have access to the folder. Checked the Samba group and config file and the user was defined as a member of the group. It didn't make sense and I then did something else for a while. When I tried again, without doing anything further about it, the user had access to the folder. I did restart the Samba server after my original changes. Thanks in advance.

• How to Add the Windows Calculator to the Quick Access Toolbar in Microsoft Excel 2013

  - by Lori Kaufman

  Do you use the Windows Calculator to perform quick calculations while building spreadsheets in Excel? You can save time by adding the Calculator to the Quick Access Toolbar in Excel so you don’t have to leave the program to access the Calculator. To do this, click the down arrow on the right side of the Quick Access Toolbar and select More Commands from the drop-down menu. On the Quick Access Toolbar screen on the Excel Options dialog box, select Commands Not in the Ribbon from the Choose commands from drop-down list. Scroll down in the long list and select Calculator. Click Add to add the Calculator to the Quick Access Toolbar. Click OK to accept the change and close the Excel Options dialog box. You’ll see a Calculator icon on the Quick Access Toolbar. When you move your mouse over the icon, a hint displays saying “Custom.” Despite the label, when you click the icon, the Windows Calculator opens. The same procedure works for adding the Windows Calculator to Excel 2010, as well.

• How can I discourage the use of Access?

  - by Greg Buehler

  Lets pretend that a very large company (revenue numbers with more than 8 figures) is looking to do a refresh on a software system, particularly the dashboard used by employees. This system was originally put together in the early 1990's to handle inventory tracking and storage across a variety of facilities (10+). Since this large company is now in the process of implementing some of these inventory processes with SAP they are in need of a major refresh. The existing system: Microsoft Access project performs dashboard duties Unique shipping/receiving configurations at different facilities require unique forms and queries within the Access project Uses 3rd party libraries referenced by Access to directly interface with at control system (read: motors, conveyors, and counters) Individual SQL Server 2000 instances (some traces of pre-update SQL Server 6.0 documents) at each facility The Issue: This system started as a home brewed inventory tracking scheme with a single internal sponsor who is still in charge of the technical direction. The original sponsor prescribing the desired deliverables that are being called for in the current RFP. The RFP describes a system based around a single Access project. Any suggestion that Access is ill suited for a project of this scope are shot down under the reasoning that "it works for the scope now". Are there any case studies, notices, or statements that can be used to disuade this potential customer from repeating their mistake? Does Microsoft make any statements directly about when it is highly recommended to ditch Access?

• Role based access to resources for a RESTful service

  - by mutex

  I'm still wrapping my head around REST, but I wonder if someone can help with any suggestions or approaches to role based access control for a RESTful service, particularly from the point of view of securing the data and how the URLs might look. It's probably best to consider an example: Say I have a REST service for Customers, and want to split the users of this REST service into Admin, Editor and Reader roles: Admins can change all attributes of a Customer resource Editors can change only some Readers can only view them. Access control rights are assigned to the Customers entities individually. So for example a user of the service might have admin rights to Customers 1,2 and 3 but Editor access to 4,5 and Reader access to 7,8,9. Now consider the user calling the service. What is a good way to seperate the list of Customers for the current User? GET /Customer - this might get a list of all customers that the current user has Admin\Editor\Reader access to. But then on each Customer the consumer would need an indication of what role they have. Or would it be "better" having something like GET /Customer/Admin - return all customers the current user has Admin access to. Just looking for some high level pointers or reading on a decent way to secure\filter the resources based on roles of the current user.

• How do I translate a point from one rect to a point in a scaled rect?

  - by Bill

  I have an image (i) that's been scaled from its original size (rectLarge) to fit a smaller rectangle (rectSmall). Given a point p in rectSmall, how can I translate this to a point in rectLarge. To make this concrete, suppose I have a 20x20 image that's been scaled to a 10x10 rect. The point (1, 1) in the smaller rect should be scaled up to a point in the larger rect (i.e. (2,2)). I'm trying to achieve this with: result.x = point.x * (destRect.size.width / srcRect.size.width ); result.y = point.y * (destRect.size.height / srcRect.size.height); However, the points generated by this code are not correct - they do not map to the appropriate point in the original image. What am I doing wrong?
