No internet access via wireless router

October 8, 2010 at 03:45:47
Specs: Windows 7
I have 2 PCs connected to a NETGEAR WN300 ROUTER, one is XP and connects via ethernet this works fine.

The other is a windows 7 laptop and connects wirelessly. I bought the latop about 4 weeks ago and for 3 weeks the wireless internet has been working fine. However since last week i now receive a limited connection warning and cannot access the internet (i can access the router and have a good connection to it).

Things I have tried without any success :

Tried different channels
Tried lower speed
Tried disabling ip4 and ip6
Nb - if i disable ip6 and enter details in ip4 manually i get the network recognised but still limited connectivity.
Tried specifiing ip manually
Tried disabling security
Tried wep
Restarted modem
Restarted pc

I have not yet tried :

Conntecting via ethernet.

Any help would be appreciated as i am at a loss.

First look at the device manager & the event viewer for errors. Then, run ipconfig /all from a command prompt. Post the output.

an update -

i tried connecting another laptop to the wireless router and this worked.
I tried connecting the existing laptop to a friends wirless and i get the same problem.
I tried connecting via ethernet and again i have the same problem (local area connects but no internet access)

This proves it is a setting on the laptop but i cannot see anything in the device manage. I have tried disabling the firewall to ensure that was not causing the problem.

I have pasted IPCONFIG ALL below and would appreciate any further advice.

It's getting an IP address. What firewalls are on that machine besides Windows? Is Zone Alarm or Norton running? Boot to safe mode & try to connect.

uncheck ipv6 in tcp/ip properties and only use ipv4. I have found windows gets confused as to which it is primarily talking on.

WIN 7 doesn't like WEP and you have to use a higher level encryption like WPA
