I've got a G+MIMO USB Netowrk adaptor on my PC with Windows XP And have a Wireless G+MIMO ADSL 2+ Modem Routor.

It's been working fine untill recently when it suddenly the connection went from 54.0 Mbps to between 1.0 Mbps - 12.0 Mbps when i turned it on one morning.
I was fine with this as it didnt really stop me from surfing the internet etc.

But then about a month or two later I turn it on again this morning and theres no connection what so ever.

I've tried check my firewalls etc but I can't find any solution.
