I have a wrtg54g v2 by my pc and a wga54g game adapter connected to my xbox and my connection is now terrible. It was good in the past when i bought them 6 months ago. Ive tried different channels and cant work out what the problem is. The setup for the wga54g says my signal strength is only about 50%. Ive tried firewalls off and reseting the router and the adapter. Im stumped as to whats causing the problem. The only thing i havent tried is updating the firmware, but it workerd in the past. Any ideas would be much appreciated. Thankyou in advance.
