USB Wifi Adapters are a plenty these days, I happen to come by the D-Link DWA-123 that’s really cheap.
Just how good is it?
The product works fine as a USB adapter but among many USB adapters that I’ve tried, it has the weakest reception I’ve ever come across.
What’s more funny is that the reception signal could be near full strength but only picked up very few SSID signals.
More details at the official product page.
It’s CHEAP! I got mine at RM 15 and I’ve seen places selling it at RM 12 or so. You can’t get any better deal for USB Wifi devices, please let me know if you do come by any that’s cheaper and of a decent brand.
On the downside, just be prepared for the not-so-stellar connection. Buy a better USB WiFi adapter if you have the funds, and especially if you want good signals.
