since building a new rig last christmas ive had endless problems with wireless networking.

specs:

asus p5q-se
intel e8400
4gb corsair dominator ram
palit hd4870 1gb
seagate sata II 500gb
corsair tx series 650w
vista ultimate 64 bit

wireless cards: d-link g510 rev C and Asus wl-138g v2

With the g510 i can get a connection to the internet but im getting only 1mbps despite 22mb internet, browsing and downloads are painfully slow.

With the wl-138g i can only get a local connection or connection with limited access.

Ive tried everything i can think of:

Wipe, reinstall and try new drivers,
tried all pc slots
removed second stick of ram
updated bios, cleared cmos
reinstalled vista

I've even installed xp on a spare hard drive and i get the exact same problems.

After all this, i thought i must have a faulty mobo so i returned it to the reseller, they told me they have "confirmed the fault" and sent me a new one.

Yesterday i put my pc back together without any cards, installed the asus drivers and put the card in, connected fine and got good speeds on the internet. I rejoiced and celebrated, thinking it was all over.

Then, this morning i booted up and i got no connection at all, after loads of tinkering im back to square one and both cards are operating like they did before the motherboard replacement.

Now, i have no idea what to try next and how to get this fixed.

Please, help me out!
 
sorry, the post was pretty long as it is, didnt want to drag it out any longer.

I have O2 22mb broadband (pro package) with their Wireless Box III Router.
 
im 1 floor up from the router and one room across so there is quite a bit in the way, not a problem with signal strength though, it is normally very good to excellent.

btw, ive just tried an old usb dongle, suprised there were vista 64 drivers for it but its so far its working alright, decent speeds not amazing but at least its a temporary solution.

As far as my other problems go, really the only thing i can do is to buy another card. Ive spent months trying to get one of these to work properly and they really dont want to.
 
I had a similar problem. Tried 2 different network cards (a Belkin and Linksys) and both got the "limited or no connectivity" problem. Tried loads of different solutions I found using but nothing worked.

Tried a friends USB adapter and worked fine so went and bought one for myself, a micronet one and it works fine as well.

No idea if its an option for you, or if it will solve your problems, but I found the USB adapters much easier and they actually worked!
 
I had signal strength issues with PCI wireless cards. I found them hopeless. Switched to USB Wireless adaptors and haven't looked back - Vista reports a full strength signal or one bar below that . Mind you I tried for ages getting the Netgear ones to work, and eventually found out they refused to work on any channel other than 1. Obviously I had the router and the cards using the same channel, but nothing would work at all until both were on ch 1.
