ASUS DSL-AC51 Speed/Sync Problem

[thedeveloper]

Hello, I was using this device like 2 months. At first everything was ok no problems at all. I have been trying to fix this device for 1 week, because i was using 35/3 speed with my ISP. The speed is gone to 0.10 for download and 3mbps upload. I restored to factory settings like 3-4 times but still same problem. I tried to change every settings i saw on the web panel but still no luck. I updated the firmware to the latest version, still no luck.

Finally i borrowed another modem from my friend, and guess what it was working very well. I literally got 35 download and 3mbps for upload. But when i reconnect my router again still same problem. I tought the problem is my computer or what else so i tried with 4 different devices, still same problem.

Tried to contact the ISP for this, all they say they cant see any problem.

How can i fix this problem ? Because i was trying to fix this problem like 1 week, searched everywhere but found nothing. I uploaded the DSL log page to the attachment.

Here is a speedtest result made today from this modem => http://www.speedtest.net/result/7509248717

Thanks and sorry for my english.

Is this YOUR ADSL modem or ISP supplied?

Am not absolutely sure, but am thinking the ISP needs to "provision" you modem, if u reset it to factory, u may have to tell them.

And if this is ISP supplied modem, well THEY would be ultimately responsible.
