DNS Resolution Failures

Message 11 of 11

Hi,

I had my Huawei router replaced in November 2021 which resolved a speed issue.

Recently I have noticed that I have to reboot my router nearly everyday as I lose the Wi-Fi.  The message on my devices is that it could not locate an IP address. (or similar).

Looking  at the logs there are pages of DNS Resolution Failure errors.

Hi Blakey57

 

The router is on its way, please allow 24-48hrs for this to arrive.

 

Please let us know how you get on.

 

Thanks

Hi Blakey57

 

Would you like me to send a replacement router for testing?

As it affects both bands you either have similar levels of interference on both bands, or there could be an issue with the router. Just in case I suggest that the router is replaced first, to see if this addresses the issue.

Hi Blakey57 and @KeithFrench

 

The WIFI optimisation has now been switched off.

 

Thanks

I split the signals to see which it was and both the 2.5 and the 5GHz bands do this.

How do I go requesting the Wi-Fi optimization be turned off.  It is getting irritating rebooting the router on a daily basis 😊

The 5GHz band only has half the range. If you want my help, ask TalkTalk to disable WiFi Optimisation first (unless it already is) & then I can help you.

Thank you for the reply.

Ironically, this wasn't a problem with my Huawei router (or any other routers that I have had).  It also seems that the 5G signal is the one that goes first.

Signal strength is good at all times.

Slow speed, intermittent dropouts, breaks in the signal or no signal on some or all devices or no internet access might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a by-product of the popularity of Wi-Fi.

Generally speaking, the 2.4GHz band suffers much more from interference than the 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

Have you had TalkTalk’s Wi-Fi optimisation disabled on your Sagemcom FAST5364 router? When this is enabled, as it is by default, it has the power to override any Wi-Fi configuration changes that I might suggest that you need to make. This will not help rectify this type of problem if Wi-Fi Optimisation is allowed to change my suggested settings. Only TalkTalk can do this for you, you cannot do it yourself. If not, just request they disable this for you in your reply.


The next stage involves sending out a guide to you to help you get me some important diagnostic results, so I can analyse them for you and recommend changes to your router configuration to solve them.

I only send this out to people who request it.
