T3 timeouts - started happening again in recent 2 weeks

Question

rabiya · Answer

Is anyone else facing internet connection drop in recent 2-3 weeks in 85044, I had to do modem reset for more than 10 times in the recent 2 weeks.

Hi @Rabiya

I know how frustrating it is to have frequent internet signal drops. Are there any splitters or amplifiers that are connected to the coaxial that is screwed into the back of your modem? If so can you please bypass any splitters/amplifiers and plug it directly into the wall from the modem?

No splitter/amplifier, directly connected to wall from modem.
