• Are all bluetooth adapters the same ?

  - by ldigas

  I have a wireless bluetooth mouse which I'm not using. It used to have a bluetooth adapter with it, which I lost a long time ago ... (don't ask). Since my regular mouse just died (bad contact in cable from messing with it too much) I was thinking of buying just the new generic bluetooth adapter ? Are all those adapters the same thing ? Or can this that came with the mouse be somehow different ? Edit by ldigas: How would one find out what bluetooth standard/class/adapter one needs ? (I don't see anything useful written on the sticker on the mouse). Or to put it bluntly - will it work with this one in your opinion ?

• Locate rogue DHCP server

  - by Farseeker

  I know this is a serious long shot, but here we go. In the past week or so, for users connected to a particular switch in our network (there are four dumb switches all connected, and it only affects SOME, not all, users on the one switch) are getting DHCP addresses from a rogue DHCP server. I have physically checked every cable plugged into the switch in question to make sure that none of them have a router or wifi point attached to it. I know the IP of the DHCP server, but I cannot ping it, and it does not have a web interface. Does anyone have any suggestions on what I can do to locate it or shut it down? Unfortuantely all the switches are unmanaged, and as mentioned, there's no physical device (that I can find) plugged in to anything. It's getting critical, because it's screwing up the PXE boot of a whole bunch of thin clients.

• USR9108 not connecting to DSL service/not detecting carrier

  - by Salman A

  As suggested in this answer I've hooked up the phone cable to the USR9108 router. I've entered the information provided by the ISP (VPI/VCI, Username, Password etc) in the ADSL configuration section but the router does not connect to DSL service. The ASDL diagnostics fail in the first step stating that no signal was found. The same phone line when connected to ZyXEL P-660R-T1 v2 modem works successfully. Can anyone tell me how to trouble shoot this issue? Does it have something to do with 2 wire and 4 wire telephone line? PS: whats the difference between ASDL and DSL?

• How do I replace the screen of a Dell Ispiron 1545?

  - by Ajus10

  I got a new screen for a Dell Inspiron 1545. The old screen says Dell Inspiron 1545 LP156WH1 (TL)(C1?) HD and the new one says Dell Inspiron 1545 LP156WH1 (TL)(C1?) LCD Does that make a difference? All I can get to work on the new screen is the backlight. The old screen had a crack. Now when I plug the old one in, it will not turn on at all. Could I have blown the inverter or messed up the cable?

• Keyboard automatically disconnects and reconnects

  - by Algorithms

  The problem i am facing is the keyboard (USB) automatically disconnects when there is a fluctuation in the power supply to the speaker. The speaker and the pc both draw power from a apc ups. The fluctuation occurs because the speaker plug is not tightly connected to the ups power outlet. It is okay for normal work, but a accidental jerk causes the fluctuation. However after some amount of time (usually within 5 seconds) the keyboard automatically reconnects and windows plays the sound of hardware connected. This problem will also occur if I manually take out the speaker power cable from the ups power outlet. My question is whether the problem I am facing is due to electrical issues, or due to software problems. PC config: OS : Windows 7 Ultimate UPS : APC 600 VA PSU : Corsair TX 650 Speaker : Realtek

• Why only the left speakers are working?

  - by user324469

  I've just bought a 5.1 speakers and only the left side speakers and the center are working. If I plug in the speakers to my mp3 player than each speaker is working, so the speakers are good. I have windows 7 and I can't configure it. Please help me! I'm sure that the problem is with some settings at the computer. A while ago I had the same issue with some stereo speakers and I can't remember how I've fixed it, but it was only a setting error. I don`t think that my sound card could be the problem, because it's in-built and I have a new motherboard: asus m2n68-am. I've just tested my computer with some stereo head speakers and also only the left one was working. If I start the speakers very loud than the right speakers are making some noise, too I've connected the speakers with a two channels cable. This is the speakers type: genius sw-hf 5.1 5050 v2

• Wireless Access Point - Can't ping other machines on the wireless network

  - by Surfer513

  I have a wireless access point (Netgear), and I have it setup so that it has an IP address in the current subnet (let's say 192.168.2.0, subnet mask of 255.255.255.0). The machine that it is connected to via ethernet cable has an IP in the same subnet as the AP. The machines that are connected to the AP via the wireless connection also have an IP address in the same subnet as the rest of the network (192.168.2.0). All machines can ping the access point, but they cannot ping each other. I don't totally understand why, because there is connection and all of the machines are in the same subnet. I realize this is a layer 3 device, but is there an issue because of this AP's lack of gateway capabilities? (i.e. no routing table, etc.)

• Using ethernet cables?

  - by Farhad Yusufali

  I have an HDTV which supports internet connectivity through an ethernet port or wirelessly (but this requires an additional wireless USB adapter, which I don't have). I also have a blue ray player than supports internet connectivity through an ethernet port or wirelessly (natively - no other devices are needed). I want to connect my TV to the internet but my router is too far away. My blueray player however is already connected wirelessly. If I connected my TV to my Blueray player via ethernet, would my TV be able to connect to the internet? To clarify: Wireless Signal - Blue Ray Player - Ethernet Cable - TV Would this work?

• Home CAT6 wiring: CMR vs CMP?

  - by Eddie Parker

  I'm planning on wiring my house with CAT6 cable. I'm finding a large jump in price between CMR and CMP cabling, and I'm confused by what counts as a 'plenum' and what does not. As I'm wiring my house, I'm planning on going through interior (hollow) walls, and through the attic and crawlspace to get to the points I wish to wire. I will be going between floors at one point, which leads me to believe I need at least CMR, and obviously CMP wouldn't hurt either. I don't mind spending the extra money if I need to, but is it overkill going for CMP if the bulk of the wires are either going vertical, or through a crawlspace or attic?

• Windows 7 randomly installs an "Unknown Device" successfully

  - by Amazed

  Rarely (several days to weeks between occurrences,) and seemingly at random, I get a balloon notification from Windows 7 (x64 SP1 Home Premium) that it is installing hardware for me. Whatever is being installed does so without error. However, no new hardware has been installed or plugged in! When I click the balloon it doesn't give me any useful information: Looking in the event log, I find this entry: Event ID: 20001 Source: UserPnp Task Category: 7005 Message: Driver Management concluded the process to install driver FileRepository\usb.inf_amd64_neutral_153b489118ee37b8\usb.inf for Device Instance ID USB\VID_0000&PID_0000\6&3AF9A177&0&0060&&02 with the following status: 0x0. It appears to be USB related. My motherboard has both USB 2.0 and 3.0 controllers. My keyboard and mouse are plugged into the 2.0 slots and the data/recharge cable for a tablet (but not the tablet itself) was plugged in to the 3.0 slot. No other USB devices have been attached for several days/reboots. Why is Windows doing this?

• Thinking of Powerline adapters for networking

  - by Henderson McCoy

• Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)

  - by Charlino

  I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p. I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?). The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable. So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen? TIA, Charles

• Toshiba Satellite laptop connected to HDTV

  - by VANJ

  I have a Toshiba Satellite A505-S6014 laptop running Windows 7 64-bit connected to a Toshiba Regza 42" HDTV with an HDMI cable. The laptop has a 16" display and the screen resolution is set to the maximum/recommended of 1366x768. The display output is set to "LCD+HDMI". The display looks fine on the laptop screen but on the TV it is not a "full screen" display, it leaves a good 3" black border all around all 4 edges. When I switch the display to "HDMI only", it is now too big for the TV screen and some of my desktop icons are no longer visible off to the side. What is the best way to set this up? I guess that since a 16" and 42" displays have different native resolutions, a LCD+HDMI mode is defaulting to the optimal size for the 16". But when I set it to HDMI Only, what is the appropriate resolution for a 42" full screen display? Thanks

• USB to LPT adapter?

  - by Dave

  I'm bummed out, pretty much all of our computers here lack parallel ports. I have an EETools ChipMax programming tool that has one of the old-school Centronics connectors on the back. I figured that someone must make a USB to LPT adapter. Sure enough, I found one from iogear, the GUC1284B that is a USB to Parallel Printer cable. Note the boldface on the Printer. It must connect to a printer -- it isn't some generic USB to parallel interface, unfortunately. Does anyone here know of an adapter that works for parallel devices that aren't printers? I'd hate to have to buy a USB version of the ChipMax when I don't need to use it very much.

• Linksys WRT54G2 not showing connected PC's in DHCP table

  - by Moose

  For some reason all of a sudden my linksys WRT54G2 no longer shows PC's connected in the DHCP table. It was being touchy then all of a sudden they all just disappeared. It showed 2 of the 4 connected then it showed the other 2 then it only showed 1 and then it was showing none. I seem to be having a connection reset every 30-60 minutes also not sure if that is related to the router going bad or if it is just comcast being it's typical crappy self. I have tried to reset my router and my cable modem and both problems still seem to keep happening(no PC's in table and connection reset every 30-60 mins). Now I know the router doesn't store clients after a router reboot but they normally show up within a matter of minutes for me in the past. Before anyone asks yes all devices on the network are using DHCP and not static. Could this be a sign of the router starting to go bad?

• DLP projector has odd colors

  - by torbengb

  At my place of work, we have several different video projectors, but they all use DLP technology, and the colors are wrong: for instance, yellow looks more like green, and all other colors are similarly distorted. Any kind of presentation or collaborative work is hindered by these wrong colors. On the laptop screen, the colors are fine but on the projector (hooked up via normal short VGA cable, and showing the same image at the same time), the colors look wrong. This is not about one specific projector or one specific laptop; it seems that any combination of projector + laptop has the exact same problem. Someone said that DLP is poor technology, but that's not true. I'm using a DLP projector at home (regular PC connected via HDMI) and the colors are excellent. Still, there's some kind of curse on the machinery at work. How can we get decent colors?

• Is this a common/bug on this PPPoE setting for Cisco ASA 5505?

  - by DCAlliances

  We have to change the way the firewall setup due to we've changed the internet provider. The way we setup we have ADSL modem and we have to do a full bridge mode and the firewall configuration has to change from Static IP to Use PPPoE option on Outside interface with PPPoE username and password, CHAP authentication, WAN IP and WAN subnet mask. [See the attachment] It's been working ok with the use of PPPoE option however the issue is that if we un-plug the power cable of the firewall. This "Outside" interface turned to blank - NO WAN IP, PPPoE username and password. So basically, we have to retype this information again. Is this common or a bug? Any ideas? Thanks

• Migrating RAID6 array from HP SmartArray P600 to LSI MegaRAID SAS 8888ELP

  - by MLu

  My customer has an external RAID6 array (8x 1TB in HP MSA60 enclosure) attached to HP SmartArray P600 controller. They have now decided to replace the server and the new one comes with LSI MegaRAID SAS 8888ELP. The HW supplier insists the migration is as simple as pulling the eSATA cable from P600 and inserting it into LSI but I'm not convinced. Unfortunately I have nowhere to test, and will have to do the exercise on the production array :( So the question in brief - is it possible to import the HP SmartArray P600-created RAID6 array to LSI MegaRAID 8888ELP?

• How can I get data off of a Corsair SSD?

  - by user1870398

  My Corsair SSD won't work and I have some critical data on it that I didn't back up (I needed to create a copy of my mechanical storage device, just forgot). The drive isn't detected by the OS or BIOS. I also tried it on another system, but all that happened was the OS failed to load (my guess was that it knew the drive was there, just couldn't read it). I tried powering it on without the data cable for a bit of time to see if it'd work again, but it didn't. Any ideas of how I can get the data off of this drive without having to send it in?

• 3 monitors + a TV on a single card with Eyefinity?

  - by Paul Accisano

  Greetings all, Right now I have a fairly standard video card with 2 DVI ports, one powering my single monitor and another powering my HDTV (with a DVI-to-HDMI cable), which are in separate rooms. I never need to have my monitor and TV active at the same time. I'm looking into a possible computer upgrade. I'd like to know if the following situation is possible. I want three monitors on my desk powered by a single card, which I hear these new Eyefinity cards are capable of. But, I also want my TV hooked up. At any given time, I would want either my three monitors active or my TV active, never both at once. So it seems to me it might be possible to do this all a single 3-port card with a splitter of some kind. Is this possible? What hardware would I need? Thanks!

• Using airport extreme base station as a wireless G to wireless N bridge

  - by micmcg

  Due to unfortunate placement of various wall outlets in my new apartment, my adsl 2 modem + router is not able to be placed next to my airport extreme base station (AEBS). I'd prefer not to run cat5 cable between them, but I still want to use the wireless N on the AEBS, because it will have a high speed NAS plugged in via gigabit ethernet so I want to maximise the wireless transfer speed to my 27" iMac. Is it possible to use one of the radios in the airport extreme to bridge the wireless G network with the router, and the wireless N radio to broadcast normally? The only traffic going over the G network should be internet (24mbps ADSL2) so it should never get saturated. Thanks

• Routing internet through ethernet to a computer without a Wireless adapter

  - by Decency

  I'm setting up a small home network. I have a laptop which connects to internet wirelessly- that works fine. I have a desktop connected to this laptop by an ethernet cable which I'd like to access the internet with. In the past, I have used a different laptop to do this and had no problems doing so. Both computers run Windows 7. I have tried setting up a homegroup and disabling Windows firewall, as well as restarting both computers. I can share data but my internet connection can not be accessed through the desktop. (I understand USB network adapters are cheap, I have one on the way but that doesn't solve this issue.) Any help or live chat support if you'd prefer would be appreciated. Thanks!

• How can I switch between the HDMI and DVI outputs of my graphics card?

  - by Owen Melbourne

  I've got an Nvidia GTX 560ti card which currently I've got my 2 monitors hooked up to using the 2 DVI ports. However its got a mini-HDMI port which I've plugged a HDMI cable in (with mini adapter) and lead it into my TV which is across the room. I'm hoping to be able to toggle between the HDMI output and the DVI outputs, however I'm not sure how I'd go about this, Could somebody please point me in the right direction, I'm not really worried about having all 3 on at the same time so that isn't a problem, but if its possible then I'll do that.
