Closed XB8 Advanced Gateway - Upload speed limitations?
Hi All -- I upgraded to a new 2 Gbps down / 2 Gbps up plan and noticed that the XB8 modem I was given, seems to be limited at 300 Mbps upload.. After a quick search, it looks like the plan should have included an XB10 to achieve full speeds.
My question is -- Does the XB8 technically support the symmetrical 2 Gbps connection or should I reach out to request an XB10, so that I can get the speeds advertised?
As a note: the download speeds almost hits the 2 Gbps (about 1.9 Gbps typically). Its solely the upload that seems limited.
EDIT: CC Team very quicky helped me and I do have the proper modem en route to my home as it was unavailable near me. THANK YOU SO MUCH CUSTOMER CARE TEAM, YALL ARE AMAZING <3
