I am currently using Linksys WUSB54G and it constantly disconnect. Can someone please recommend me a wireless pci adapter that is in an average price and stable ?
Are you sure it's not your router that disconnects, not the USB adapter?
Anyway, I'm using an Airlink 101 Wireless PCi Adapter that I got from Frys for on sale $10. It works great and if you have a Fry's nearby, then I recommend you get the Airlink when it's on sale.
I don't think it's my router problem because my laptop has a built in nic card and it is working fine. BTW, I have a wrt54gs v1 router with the latest firmware and I am also using HyperWRT as well.
