WiFi - Limited or No Connectivity

divine · 16-07-2008, 00:42

Since changing my graphics card (and in the process shifting my WiFi card down a PCI slot so the graphics has more airflow) the WiFi has been acting up.

For the first half an hour or so, it was fine, then it dropped the connection and hasn't connected properly since, despite three reboots of the PC and the router.

I'm really at a loss as to why it would stop working completely like that.

I'm tempted to reinstall the card but on initial install it said to not put the card in before the drivers. Will this really matter if I were to uninstall the drivers and reinstall them, or newer ones if I can find any, will I have to take it out, install drivers, put it back?

In 99.9% of cases, the reason for that warning is simple. The software or instructions assumes you haven't been through the New Hardware Wizard. So long as you cancel the wizard every time then it rarely matters what order you use. Worst case it'll just not work - it's not going to burn down your house and send terrorist messages to GCHQ if you don't follow their instructions to the letter.

PS - before you go tinkering with hardware, completely shut down both the PC and the router, wait 30 seconds, power up router, power up PC.

meh, it's working again now, all of it's own accord, I just went to bed and thought i'd fix it today and when i woke up it was working :/

Over heating from the gfx card.

If you have changed pci slots. I would most certainly. Wipe it and reinstall the drivers/software.

This will show you what every network channel is. You don't want it the same. You can then play around with the channel number till you get the best signal.

For 802.11a/b/g ideally you want to be 6 channels away from your nearest neighbour(s). Usually far easier said than done though.

Its usually quite easy as most stuff hangs around the same channel, or thats what i find here anyway. My router can scan the channels and tell me whats using what which is a nice feature.

Oh that's a very useful feature, what router is it?

Its the WRT54GS (version 0,1 or 2 linksys's best). Had to buy it in german and flash it with an english firmware first, then i put Tomato on it. Loooads of features, half i don't use, but quite a few come in handy
