You can change them over the counter at a verizon store
or something that a lot of people have had good luck with is changing the wireless frequency. you should try that first.
log into the router @ 192.168.1.1 -
user name admin
password is the serial number under the upc barcode of your router (case sensitive) unless you have the dual antenna router, and then its labeled login password. again case sensitive.
once you are logged in, stay inthe first column and click change wireless settings. and then look for channels,
change it from auto to 1, save/apply and test.. if its better, leave it there. if its the same or worse, try channel 6 and then 11, rinse and repeat.
worse case scenario I use the trendnet wireless n upgrader and its cheap and works very well.
