Suggest Wireless USB Adabter

We have worldcall wireless modem in our house. Currently I'm using Realtek USB adapter to connect to my wireless modem. From last few days Wireless usb is giving up, sometime it doesn't pick and from last 2 days it is giving me 10kb speed on 512 MB connection.

Kindly suggest me some best USB wireless adapters with best signal strength and please include price too if you can. By the realtek cost me around 1400 from sasi arcade.


linksys routers and usb adapters are the best for wLANs imo.

i believe their usb adapter costs around 1.6-1.8k
