Found on routers web page under status.What ISP Service do you have? Cable or DSL?What ISP Modem do you have? Stand Alone or built in router?What ISP Modem make and model do you have?
Glad your here man. Will try to help you out as much as we can. The HW version can be found on the sticker underneath the router itself. Let us know how Single mode G works for you. Any other WiFi routers in the area? Use InSSIDer to find out.
