Laptop PC unable to access internet/ping default gateway on wirless

[andy.hewitt]

Hi Guys

Hope you can help as one of my PCs is causing me huge issues at the
moment.

I've got a Belkin modem/wireless router connected to a vista pc via
network cable and 3 other laptops via wireless. All work fine and
connect without problems except the HP Laptop.

The router allocates IPs via DHCP and has a default gateway address of
192.168.2.1. The HP laptop will obtain a wireless signal,
authenticate and connect with the network ok but that will be it. It
may occasionally work for 2 seconds but after this all connectivity
will drop out and I will be unable to ping the default gateway. I can
ping the computers own IP and 127.0.0.1 but nothing else.

I have completed stripped all software/spyware from the machine and
done a clean install of windows. I've disabled Windows firewall and
no other firewalls/security software are installed. I've also run the
winsock fix software and tried hard coding the IP details too but
still haven't got any closer to fixing this.

Below are the ipconfig details:


Ethernet adapter Wireless Network Connection:

And for comparison the details from a working pc. As you can see the
only differences are the model of network card and the ip details.

I'm really running out of ideas now, the only thing i can think of it
that the on board wireless maybe faulty? Does anyone have any
suggestions before i completely go insane?

Thanks

Have you check to see you may have press a button that disable the wireless
connection. Laptops generally have a button that can eniable or disable the
wireless connection as well as some models have a software disable also.
Check your manual to see where the button is on your laptop.

If your laptop is an older version the issue maybe that the Belkin
modem/wireless router maybe set for only G protocal and is not allowing B
protocal. Check the manual for your router to check to see if that maybe the
issue.

Good Luck.

Hi Gene,

Thanks for these suggestions, however I'm not sure if i've been clear
enough. The connection will physically be kept alive by the laptop,
there is just no throughput from the it. I never actually lose the
connection betwen Laptop and router, this is always active with a
connection speed of approx 36mbps and good signal strength.

To me it seems like a firewall of some kind restricting the connection
but I've wiped the machine and disabled all default security settings
but still the problem persists. Btw, If I plug a network cable into
the side it works fine, its only an issue on wireless.
