Internet Signal is Constantly Dropping- T3 Errors
I got my Xfinity service installed on Wednesday, and I have not had a consistent WiFi signal since. The WiFi will briefly connect and then drop again after a short amount of time. I have run through all of the troubleshooting with Xfinity agents, and I have also done the same with the router company. None of the troubleshooting Xfinity has given me has worked long term, and an agent said they would send a technician to my house and that never happened. I have attached an error log from my router, but I am looking for a long-term solution so that my connection is stable enough to actually use my WiFi.

For a test, does a computer hardwired directly to the router / gateway device with an ethernet cable have the same problem ?
Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

The downstream power levels range from 0.3-0.6 dBmV, the upstream range for power is 43.0-43.4 dBmV, and the SNR goes from 37.8-38.2 dB.

I do not have an Ethernet cable to do that test. The router is continuing to have the same problem after troubleshooting with 2 different Xfinity agents today.
