Router Interference

[GraemeMcD]

Hi

Seem to be getting some kind of interference on the Router (Wifi Hub).

Generally Fibre35 gives me a solid 12-17 Ping with 30Mbps down 6Mbps up.

However I keep getting intermittent drops to 500+ Ping with single figure Mbps down and less than one Mbps up.  Particularly noticeable on XBox with online games dropping out or lagging badly.

Tried both Wifi and direct Ethernet connection between Xbox and Router and it seems to persist.

I may have narrowed it down to either or both of TV (older plasma) and/or Sky HD box but it's so intermittent its difficult to be certain. 

It also happened a couple of years ago and a replacement router seemed to fix it until now, could it be this replacement router has developed a similar issue?

Grateful for any ideas!

Hi @GraemeMcD You welcome, please keep us updated on how it goes.

[GraemeMcD]

Ok, will monitor and see how it goes with the xbox online gaming dropout issue.

Thanks for your help.

Perfect!

I think there was a previous firmware update, but I can't remember which. It wrongly set the router to have the TT network DNS servers assigned to each client via DHCP. The correct way is to tell your PC to use the router as its DNS server and the router talks to Google DNS for any queries that it cannot answer itself.

@KeithFrench Thanks for helping out.

[GraemeMcD]

that's all done.

ipconfig/all now shows DNS servers 192.168.1.1

Hi @GraemeMcD 

Look at my post #11 that will sort it.

[GraemeMcD]

Disconnected and reconnected.

Tried to pm the details as requested but apparently I've reached the limit on the number of pms I can send and need to try later!

You would've seen the router network page showing DNS 8.8.8.8 & 8.8.4.4 and the ipconfig/all showing DNS 79.79.79.79 & 80

Thank you @KeithFrench

Hi @GraemeMcD 

Our last posts crossed in the ether! I have seen this with another customer. In that case, in the router, go to:-

Dashboard > See Wi-Fi Settings > Manage Advanced Settings > TalkTalk Wi-Fi Hub > DNS

You will find the 79.79.79.79 addresses there. Delete them both and replace the primary one with 192.168.1.1 or, if you have changed it, the new IP address of your router.

Hi @GraemeMcD 

Please can you disconnect your PC from the WiFi & then reconnect it & then PM me again with the ipconfig /all command. The easiest way is to select all of the text in the commands output & use Ctrl+c to copy it to the clipboard.

[GraemeMcD]

Do I need to reboot anything - ipconfig/all still showing DNS 79.79.79.79 even though router dashboard says 8.8.8.8?? 

[GraemeMcD]

Ok - I've manually changed DNS IP4  DNS 1&2 to 8.8.8.8 and 8.8.8.4 as advised.

Guess it's just a case of monitoring now?

Presumably this will highlight an issue with Talktalk DNS servers which will need addressing and once that's done I change back to auto-select?

Hi there @KeithFrench Thank you very much for assisting the customer.

@GraemeMcD Please attempting to do anything, please confirm if the above steps helped in resolving your issue Thanks

[KeithFrench]

Just to summarise some diagnostics I have been doing with the customer via PMs. The problem initially at least, looks to be when the latency is OK, a trace route for the distant URL resolves to one IP address & when bad it resolves to a different IP address, causing the route through the internet to change. This might be a TalkTalk network DNS server issue.

This is what I have asked the customer to do:-

Try Google DNS instead (8.8.8.8 & 8.8.4.4). Log into the router & go to:-

Dashboard > See internet settings > Manage advanced settings > Internet connectivity > DNS IPv4

To use different network DNS servers (Google DNS in this example), change the DNS dropdown box to Manually Specify DNS. Then set DNS 1 & DNS 2 to the Google DNS IP addresses above.

[KeithFrench]

The strange thing here is that the two trace routes (bad & good) are resolving different IP addresses for the destination xboxlive.com. I am waiting on the customer to do some more tests for this. In light of the differing speed test results in the previous post, there may be more than one issue here. Once I know more, I will ask TalkTalk to resolve this for you, telling them exactly where the problem lies..

[GraemeMcD]

Here’s a couple of Speedtest App tests, the first with the high ping problem and the second without.

will do

Can you send me a trace route of this in a PM to me (to preserve your privacy), then I should be able to prove where the fault is?
