I'm not sure how many of you have faced this problem, but this is like an everyday occurence for me. I use the MTNL 450TC1 (but i am thinking of upgrading to another which i chose in another thread). Now, i do not use the ethernet cable, only Wifi. Occasionally, the Internet light on the router vanishes, sometimes for minutes, sometimes for hours. It's really annoying. The only way i know to fix it is to call someone, mostly call myself, with the landline. This reactivates the Internet light. However, about half the time, the light vanishes again after some time. I read online that a permanent fix to this is to buy a new router. Is this true? And, is there any other way of fixing this that does not include buying a new router?
