Xfinity/Comcast - CAX80 - Wifi speed went from 400 to 40 after newest firmware (help!)
Ever since the new firmware V2.1.3.5 upgrade (which I've confirmed is what my router is currently running), my wifi speed has dropped from ~400MBPS to ~40 to ~60MBPS. I've hard wired my computer to ...
Just checking to see if you have any thoughts based on my answers? Thank you, Eric
What's strange is, if I do a speed test through an internet browswer, I should 30-80mbps. However, using the Nighthawk app it shows >300mbps consistently. The 30mpbs is the "actual" speed though, as I'm consistently losing/dropping facetimes, TEAMs video calls, etc.
Ok so please understand. NH app only gives notification of the router side FW update only. Modem side FW comes from ISPs and they only push that when and if there testing completes. Modem side FW IS not user updateable. The router side FW is user updateable.
Users are encouraged to update the CAX using a PC or laptop and manually download FW. Users can ignore the NH app if they want to.
Though we've seen some issues on the 5Ghz side of this FW:
You might try using v.4 of the CAX80 router side FW and see if this helps any.
Users are encouraged to contact NG support and let them know what your seeing. I believe this is a NG issue and not a ISP issue. My 2 cents.
Im getting good speed with my CAX80 on recent FW however mines now back in modem only mode until NG fixes the wifi issues:
