I have an Arris DOCSIS modem on Comcast
Software Image Name:AR01.05.020.13_032624_735.NCS.20
Model:G36
The upload speed has been poor since I purchased the modem last year. 5-6 Mbps is typical
Download speed is 700+ Mbps. My previous rental modem from Comcast got around 300Mbps upload speed. Comcast came out to check the connection & found no problems. When the technician connected hist modem, he got about 320 Mbps upload.
Do a need a replacement modem from Arris?
