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

- Router firmware
- Wireless card settings in laptop
- Wireless card driver in laptop

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

No other wireless client on the router has issues.

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

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.
 
OK, I'm thinking aloud here, but if other laptops on the router are fine, then it must be specific to the settings on this laptop. The behaviour suggests that the wireless transmitter in the laptop does work, but there is a setting that is restricting the amount of data transmitted. I am not sure what this setting is but if you look in detail at the Wireless Adapter's Advanced Properties in Control Panel you may find there is a setting that can be tweaked. Transmitter power is one that comes to mind.

Other random thoughts:
- Would it be worth trying a spare USB wireless network adapter on the laptop.
- Could it be related to the way the router assigns IP addresses to the computers on the network? Is there a setting in the router firewall that could be cutting the upload off??
- Could it be related to IPv4 versus IPv6?

Probably not that much help but it might give you food for thought ...

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

Good plan, will do that on Tuesday.

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.
