Router DNS problems
Over the last week my router keeps loosing DNS connection so my devices are unable to connect to the internet.
The router connects to broadband shows a solid white light but my devices show no internet connection almost certainly because of the lack of DNS
tracert finds 188.8.131.52, the router shows a DNS connection to 184.108.40.206 but 220.127.116.11 times out
The router shows version SG4K10002816t
Powering off the router for a period resolves the problem but then at some stage DNS is lost again.
This post indicates there is a known problem with this router and version SG4K10002816t.
I suspect the problem has resulted from a version update on my router but I have not been able to find the router logs to see when the router was updated. As a result of this problem my internet connection is now unreliable. I have tried Automatic DNS setting using Talktalk 18.104.22.168 and Manual settings using Google 22.214.171.124 and both settings exhibit the problem.
I think I will need a replacement Router to solve this problem.

Broadband download speed between 15:00 and 16:00 on 26th March 2021 30 to 40Mbps then with no changes to my connections or equipment the broadband speed had increased by 18:41 on 26th March 62 to 68Mbps. See attached file Tests via 5Gbps WiFi

This morning the download speed was 68Mbps but after the rain today the speed has halved to between 30 and 40Mbps. Turning the router off and on again, using different SSIDs and connecting the router directly to the Master socket test connector, eliminating house phone connections, did not restore the 68Mbps.
The Service Centre test shows no problem. I suspect the connection from the cabinet to the master socket and that later today or tomorrow the speed issue will resolve so I will monitor the actual broadband download speed rather than the indicated speed on the router dashboard of Download: 71.01 Mbps and see what happens.

I have not changed the SSID's on the router, I assume you are suggesting using different SSID for the 2.4GHz WiFi from the SSID for the 5GHz WiFi.
With the same SSID the 2.4GHz WiFi speed appears to be 195Mbps and the 5GHz 1560Mbps

I Have not noticed the speed being halved since I restarted the router last week. I can only test WiFi speed as my PC has no Ethernet connector. The speed had dropped to 58Mbps this afternoon but after another router restart the speed is now 68Mbps, the 5GHz WiFi signal strength remained at the same level after the restart.

Yesterday the Huawei Router download speed halved but recovered as soon As I restarted the router, then the speed increased to 68Mbps again, see attached test results. I have not seen any DNS Issues with the Huawei Router.

My master socket did not have a filtered face plate which is as it was when we moved here, so until today so I had been using the external filter supplied with the TalkTalk Router. I found an old filtered faceplate from our previous property, which is unfortunately cracked, but I have now fitted this filtered face plate to master socket, this seemed to have increase the download speed from about 52Mbps to 68Mbps (upto 75Mbps for the Sagem router)
My fastest PC has 5GHz WiFi but no Ethernet connector, but since I am now getting 68Mbps for the Huawei Router or 75Mbps for the Sagem Router I am sure WiFi is not an issue.
I tried an older PC with 2.4GHz WiFi which also has an Ethernet connector the download speed via the Huawei Router was about 35Mbps for WiFi and the same for an Ethernet wired connection.
Before I received the replacement Huawei Router and I was having problems with DNS issues on the Sagem Router the download speed test showed about 56Mbps.
I will now leave the Huawei Router connected and check that it is ok over the next few days.

After your line test today the Huawei router connection speed increased to 50+Mbps, after replacing the Master socket unfiltered face plate with a filtered face plate the download speed increased 68Mbps from the Huawei router to my PC over 5GHz Wifi and 75Mbps from the Sagem router, there is now less difference in download speed between the routers so I will leave the Huawei router connected and check it is stable over the next few days.
Up until today I was using a filter connected to the face plate of the master socket to connect the router and phone.

I've completed a line test which hasn't detected any faults and your line is in sync at 51mb.
What speed were you previously receiving? Are you running a wired or wireless speed test?

The Huawei Router speed is still variable and fails TalkTalk speed test, where as when the previous Sagem router with DNS issue is connected the speed is faster and more stable see attached A4 showing tests run on Saturday plus the picture showing speed test on the Huawei which has been connected since Saturday.

Thank you for the replacement router.
The replacement router is connected and has been working for 2 days without loss of DNS but currently the download speeds are unstable and on average 10% to 20% lower than the previous Sagem router. I will monitor the router for a few days.
