SAGEMCOM FAST5364 incorrect firmware back-revision

crustyg — Fri, 08 Apr 2022 07:30:03 GMT

Hi: Since before 07:00 Wed 6th April no Internet. Have done diagnostics with firstline, they've referred me to second line. Nothing has changed my end, L2 is up, router gets DHCP address so L3 outbound is working. No packets leave from inside my network.

Finally noticed that someone has changed f/w on my device to SG4K100136 which IIRC is the oldest I ever saw. I *was* on SG4K10002808t. Screenshots to prove it.

So either I've been hacked or TT has messed up.

Please update f/w on my device to status quo ante - ASAP - as I've been without broadband for nearly 48h. Thanks.

Hi crustyg

Firmware version 136 is the latest firmware being rolled out.

Was your previous firmware 2816?

Hi Debbie: Yes, I was on 2816. Thanks.

Hi crustyg

I can try a different FW (this wont be 2816) Are you happy for me to do this now?

We advise to leave the router switched on without rebooting whilst we update the FW.

Thanks

Hi Debbie: what I'd like is the solution most likely to get me back to a working system. Why that can't be f/w 2816 isn't clear.

I'm not impressed with your QA if an unannounced f/w upgrade breaks things - and your staff can't spot it. I've wasted a lot of time and effort on this, I have two folk who are WFH affected by this and I'm guzzling through mobile data allowances trying to work. Yes, I'd like changes aimed at fixing the problem that TT has created done ASAP, please. It's not as though I'm able to use my TT connection for anything....

Hi crustyg

FW 2816 is an older version now so we wont be rolling back to this.

Firmware 136 is a new FW version and this fixed an issue with DNS reported on the old firmware.

The only reported issue we've had with 136 is VPN not working, but this is only with certain VPN clients and is not affecting all customers. The fix for this at the moment is FW 2829.

Thanks

I have a bunch of different machines that use, from time to time, several different VPNs from different vendors. But the updated firmware doesn't pass L3 traffic from my side to public side with, or without VPN.

Hi crustyg

Ok, would you like me to try the 2829 FW for you?

Yes please.

Success, L3 traffic now transits the updated device. Thanks.
