I have an Accer 4730z and I am unable to connect to my home wifi network. It will run on lan but not my wifi. When I try to log on to the Internet it says that it has an excellent connection, however when I open the Internet browser Internet Explorer/FireFox I receive an error message that says its unable to establish a connection. I took the laptop to the techs at staples and they were able to fix the problem. Apparently one of the isp settings was wrong (box unchecked). However When I arrived home home and tried the Internet it gave me the same results as before. So again I took it to Staples and again it was the same issue and they were able to resolve the issue. After walked out of Staples I tried to connect to there wifi from the parking lot and it worked, I then drove to Starbucks and was able to successfully connect to there wifi. When I arrived home I wasn't so lucky. I checked all the settings and they were in the correct positions (I have tried all combinations) I drove back into town and tried it at my cousins house who has a different service provider and it did not work. I drove back by Staples and Starbucks and it did work??? I am truly baffled, I have up to 7 computers running on my home network and have absolutely no issues with any of them except this little Accer. If anyone could help I would greatly appreciate it. Thank you
