Slow speed in new router
Hi, I replaced an old router by archer c64 router. But after some time I realize that my internet worked very slow. I checked the speed in speedtest.net by ookla. The speed in singapore servers were same (around 1 Mbps).
Not just speed checking, I tried downloading movie, and the speed was less then 20% of the usual download speed.
Then I reconnected the old router and it worked fine. But after reconnecting new router, I got the same problem. I called the ISP. They checked the modem and the whole connection, it was working fine.
I searched about this problem and got a solution that is MAC cloning. I cloned the MAC with the old router MAC, but it gave me no result. My ISP was not handling my connection with MAC so basically it doesn't help me. What can I do now?
