Asus rt-n56u WiFi & Speed problem

[Airbender1]

Hello,

My issue is that Asus router i have keep dropping WiFi connections and on top of it if i turn on my pc
then the entire network goes down.

I updated-ed the firmware no luck , i change setting to simple networking with asus setup manager that comes with web GUI and no luck. i got a repeater but still buffering issues and wifi randomly disconnect.

so i got Linksys E2000 and i put DDWRT on it and set it up as WiFi Repater but still no luck

I sent my routor back to ASUS they send it back to me saying no issue found

I did almost everything i can think off to correct the issue with no luck


Please advise

Thanks
