TalkTalk WI-Fi Hub Sagemcom 5364 version SG4K10002816t
I've had several instances of individual wired connections to the router locking up. Doing a SW reboot on the router or power cycling it fixes the issue. As near as I can tell the router is otherwise still working. The other wired connections and the WIFI still work fine when in the "locked up" state. When in this state one wired connection only locks up. Also its not always the same physical socket that locks up. It appears like the NAT table on the router for that socket has frozen.
Is there a more recent version of the firmware I can try ?

Thanks I have installed the replacement router, It appears to be working OK, the typical failure time has been in the order of a month.
I will monitor the replacement and see if the lockup recurs. I cannot be more certain about the time to failure because my son have discovered he can reset the router to restore his internet connection and is less patient.

Also when the Sagemcom port connecting to the Router froze the Port connecting to the HUB was still working and the devices on the HUB were resolving and Pinging 22.214.171.124 Ok

I have added my Phone number to my profile. Both of the ports that have experienced Lock-ups on the Sagemcom have LAN cables connecting them to a HUB and Router respectively. When the port connecting to the HUB has locked all devices on that HUB failed to route to the Internet pinging 126.96.36.199 also would not work. When the Sagemcom port to the Router is locked all the devices on that Subnet were disconnected from the internet (and could not ping 188.8.131.52). I don't think it is DNS resolution because pinging 184.108.40.206 was not working in either scenario. When the port connecting the Subnet Froze all the devices on the Subnet were still visible to each other. When the port connecting to the Subnet froze I used a Laptop on Sagemcom WIFI to prove the internet was visible (DNS was resolving on WIFI) I also used that laptop to reset the Sagemcom Router with the diagnostic tools menu to clear the fault.

There is a known issue with that firmware version that can cause DNS resolution to stop working, but that does tend to usually affect more than just a single device.
You could try a factory reset if you wanted to by holding in the reset switch on the back for over 10 seconds, however this would lose any settings you may have ever changed in the router.

There is a newer firmware version, but the rollout is currently paused whilst TalkTalk investigate an issue.
