Sagemcom FAST 5688W
Until a couple weeks ago working perfectly. My wife and I work from home and are now unable to connect to our corporate VPNs. Needless to say if this issue is not fixed very soon we will be canceling our T-Mobile home internet.
Exact same situation here. Last week was the storm. Everything was working perfectly fine then the day after the storm, VPN is an issue up to now. T-Mobile rep is no help.
Tried the suggestion:
2.4 GHz, and select WPA - Did not work for me
2.4 GHz band > select WPA/WPA2 > WPA “TKIP & AES” - Did not work for me
I might end up switching Internet promptly because it's an issue especially when you work remotely.
I’ll search around if I can find other tips
