We have started receiving more calls reporting connectivity issues since upgrading our firmware. As a result, we have decided to roll it back across the entire network. Most problems reported involve clients below the CPE having no internet access even though the CPE itself is connected. The only way to resolve it was to reboot the CPE, and i was becoming too much.

Hi @arcsak,

by any chance, do you have techsupport file from SM if it was reachable during the issue?
Or PM me, please, techsupport file just to see your configuration!

We’ve updated all of our e1k/e3k radios to 4.8 and haven’t experienced any issues or customer calls. We’re using a static IP and NAT on the SM’s. What sort of settings are you using on your SM’s?

Is this the latest for the Force 180?
Can I go from 4.61 directly?

Hi, @Shaun_Dee
Yes, 4.8 is the latest stable firmware for ePMP AC and N devices. You may use it to upgrade directly from 4.6.1 version.
