Nighthawk x4s C7800 w slow speeds from Xfinity Gigabit
Hello! I've had my C7800 for a little over a year with Xfinity Gigabit as my ISP. When I first got it, I was getting wired connections around 800+ Mbps, 5Ghz WiFi at 400+ Mbps, and 2.4 Ghz Wifi ...
Hi, I have a new 1 gig service from Xfinity and with my brand new C7800 I am experiencing the following speeds:
S9+ Cell phone on WIFI 5G - 350 Mb down
PC Windows 10 on WIFI 5G - 60 MB down
same PC on wire directly from router - 30 MB down.
I have checked all cables and had Xfinity reset my service (which did nearly double my previous speeds to those listed above). I don't understand how my wired speed can be slower than my WIFI. I can't find any settings that would explain this. Any help would be much appreciated.
Thank you,
What are your wired speed results with a wired PC and ooklas installable speed test app?
Do you happen to have a different wired PC to compare tests results with?

Hello I purchased Nighthawk Xf2 c7800 and my wired connection shows the speed at 150mbps but wirless 5G has 400mbps and 2.4 has 60mbps. I have Xfinity 1g plan. I used to have Arris surf pro prior to this one and I used to get 500mbps on the wired one. I am planning to return my C7800. Any input to resolve this issue is highly appreciated. thank you.
Try a different wired PC to compare wired speed results.
Wireless devices will max out at aroun 400-500Mpbs on 5Ghz AC. You not see anything near 900Mpbs. Wired you should.
Be sure the ISP has provisioned the modem correctly for that speed package.
Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
