ARCHER C6 disconnecting from the internet.
Hello Internet, I have an Archer c6 (v2 EU) running the latest firmware 1.3.6. The internet connectivity LED shows red every 2-3 minutes. When it is green, upload speeds are almost zero. I initially argued with my ISP (Railwire). They eventually told me to connect the modem with PC using a dial-up connection directly, and my wonder (and shame) the internet works just fine. So ISP isn't at fault here. The only flaw is the router. I had done a factory reset, changed the cables, did everything I possibly can. I don't even have a spare router, and I'm stuck with no wifi around the house. Please help me out.
