Wireless issue, wont upload...

[Dano]

Ok, this one currently has me stumped...

Plugged in via ethernet all is good, remove ethernet and connect via wireless to the same router and it will not upload data above what it needed to submit web page requests. So it will browse the web but doing a speed test over at say speedtest.net will just sit on the upload and do nothing (works just fine via ethernet). Emails can be recieved but not sent (ok, they do occasionally go, but it is very intermittant).

Everything works just fine using ethernet, other wireless clients also work just fine.

Wireless card dying maybe? Opinions please

Thanks.

Started a few weeks ago according to the client.

Most likely to be a software issue IMO. I would investigate:

- Router firmware

No other wireless client on the router has issues.

- Wireless card settings in laptop
- Wireless card driver in laptop

All appear to be normal, have uninstalled and re-installed the card to no effect.

Has any software recently been updated that could have caused this? What OS is the laptop running?

Not that the client was able to inform me of, the laptop exhibits the same behaviour in safe mode with networking too.

It's running XP.

Pretty much the same way my thoughts went, transmit power was at max, power saving was at minimum and sadly my USB wireless adapter could not see the network as it's a crappy one that doesn't like WPA-PSK, I have also been unable to access the router as the muppet who set it up for them left zero documentation other than the SSID and access key and I really don't want to be messing up their network just to rectify a fault on one laptop.

I'll be bringing it home next week so I can see what it does on an open network using a USB adapter.

Well I disabled Norton and XP's firewall (both were running as expected...) to no effect.

Try manually setting a low negotiation speed, something like 1mbps, and work up from there. I'd say it was a bad auto speed negotiation.

Good plan, will do that on Tuesday.

Linux LiveCD would eliminate any Windows configuration issues in one swoop. Whether the wireless will work is another matter.

Another good plan, however if the wireless wont work then it will a pointless excercise

Well suprise suprise... it turned out to be Norton.

Even with all it's firewall functions turned off it was still blocking outbound traffic.
