I had some pronlem with my unifi (Biz5/VDSL)
The internet was down last Thursday,so i did the standard troubleshooting; replugged the cable and restarted the modem/router but problem was not solved. I called Ubifi tech team,but they said the report could nit be created since my application was still procrssing. Frustated by the answer,i turned off both BTU/router..
When i was going to go to bed,which was about 30 minutes after the incident,i turned both equipment, and suprisingly,the internet went back online. I was very excited. However,it didnt last long as 5 minutes later, the internet went down again

The next day I lodged again a report with TM. They asked me to check on the phone for dial tone, and there was dial tone. She asled me to changed some setting on DLINK setup page (wireless channel,to be specific) and I did. But it didnt help to solve the problem.
Now,is my conclusion correct that the root cause is the router? How can I access the Huawei to check my DSL status and parameters? If i were to flash it with DDWRT,will it help tp solve it.. I dont have the IPTV, so not an issue. Plus ive been using DDWrt for many years.. And was very satisfied with it..
Anybody here has similar problem like me?
Thanks..
