My router setting and wimax configuration everything is correct and I able to access internet connection, but only for few minutes and then again it get disconnected and I just have to try my luck to access internet. BSNL service guy had come and checked everything and said there are two WiMax base station that is creating this problem. My place is in the middle of both the base station so, it is getting almost equal signal from both and switching from one base connection to the other. Is there anyway to configure manually which base station to connect, may be something to do with frequency ?
