Hello everyone please could you help me: I have a DSL-2640R router and want to connect wirelessly through an adapter. The ethernet connection works fine. I have phoned TalkTalk numerous times but they haven't been able to solve my problem. I think I need to but in my Network key on the adapter screen wireless network properties, and if so how do I find my network key? Have looked by putting 192.168.1.1 in address bar but can't find it. Any help would be much appreciated.
