Wireless internet connection connects but internet does not work (no packets received). Wired does.
- by Rodney
When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine.
If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly)
I have tried the following:
Turned off anitvirus and firewall completely.
Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength.
Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing.
Compared all wireless settings to my laptop.
I can ping google.com and it replies (sometimes with packet loss)
When I reboot the PC it will connect for a minute or two (random time) and then just stops again.
I tried Firefox, IE etc. no joy
I have updated all latest versions (Netgear WG111v2) and drivers
Checked Event Log - nothing unusual
Ping the router (and even connect
as admin for the few minutes when
the internet does work)
Changed the MTU down to 1200 using
DrTCP
Checked Device Manager for
conflicts - none.
I ping the router from the PC
(192.168.0.10 - 192.168.0.1) and
it replies with 4 packets. BUT, on
my router admin page (which I
access via http on my laptop
wirelessly) - if I ping
192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12
works fine)
My router admin page shows the
leased IP address for 192.168.0.10
(ie it is definitely talking to the
router initially)
Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall.
It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP.
As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work.
I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter.
Thanks in advance!
UPDATE:
The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang).
