Archer c6 keeps disconnect and dropping speed
Hi,
My english is very poor but i'll do everything to explain my problem.
I had 2 routers archer a6 and archer c6, bought one of them [a6] when i got my new internet lightspeed 900Mbit/s. In the beggining everything was fine, but after one month or two internet kept dropping my speed from 900 Mbit/s to 100 Mbit/s so i had to restart it to bring my speed back, but after few hours it was happening over and over again. Still didnt care much, but then router started randomly disconecting (orange diod on router) disconnect overy 20 seconds or so, in the begging i thought maybe thats from my internet host side but when i connect my internet straight to the pc ( without using router) problem was solved. Im using ethernet cable but also wifi to tv etc. It disconnects everywhere.
So i bought another router which is called Archer c6 and everything was ok in first one month, and then internet is dropping and disconnecting again, it looks its not from the host side because connection straight to the pc without router works ok.
How can i solve my problem? I have latest firmware,i was trying to restart everyrhing nothing really helps.
Please help me
