RADIUS Authentication Problem

JThornton — Thu, 23 Mar 2023 09:57:05 GMT

Hello

I have had no connection since the early hours of Tuesday 21st March. I have inspected my router logs and there is a RADIUS authentication problem. Attached is the relevant part of the log showing a connection attempt (I have redacted my telephone number from the log).

Thanks,

John

Morning,

I'm sorry to hear this. Can I just confirm, have you tried factory resetting the router and then resetting this back up again?

Thanks

Hello

FYI I don't have a TalkTalk router since my account is quite old. I have tried resetting my router and ensuring the authentication settings are correct. I have also tried a spare router with the same settings. Both these routers were previously working correctly.

Thanks,

John

Hi John

Thanks for your reply.

I've tried a few different things but the line is not authenticating.

I think we should send a replacement router just for testing, would it be ok for me to arrange this?

The TalkTalk router can just be connected without entering any settings (not like a non TT router)

Hello,

Yes, if you send a replacement I'll give it a try. I would be interested to know what has changed, though, since my current router is set up as per the instructions on the TalkTalk web site and has worked for several years without a problem.

Thanks,

John

Hi John

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

Let us know how you get on.

Thanks

Debbie

FWIW my connection dropped around 00:50 same date and I had the same problem in my router logs : - CHAP : login to remote failed, please check user/pswd. Just got in from work today (Fri 24 March) and my connection is magically back up.

Like you I'm on an old inherited account (Pipex), been using same user/password for close on 20 years never seen this problem before. I

don't have a TalkTalk router either but have accumulated a few over the years and and all were giving a similar message re ERR-No-Radius-Rule and CHAP Authentication failed.

Hello Mike,

Thanks for your input. This confirms my suspicions that there have been some configuration changes at TalkTalk's end. I'm also from an old Pipex account and have never experienced a problem like this before.

I received a TalkTalk router, and this successfully connects and authenticates, but on trying to navigate to a web page the browser redirects to www.passwordhelper.talktalk.net. I've had a quick look for similar problems in this forum and it appears that this is again related to RADIUS authentication.

Incidentally, I tried the PPP authentication details from the TalkTalk router (01warehouse@talktalk.net/01warehouse) in my existing router and it successfully connects, but I then get the browser redirect problem.

I'll respond to tech support tomorrow with my findings.

Morning,

I'm sorry for the delay. Can I just confirm, are you still unable to browse any sites with the new router?

Thanks

Good morning,

I received the router, thank you. It connects successfully but when trying to open any web page the browser always redirects to www.passwordhelper.talktalk.net. There are several posts on this forum mentioning this problem and it appears to be related to an authentication issue.

On this thread one of your colleagues solved this by getting the network team to rebuild the RADIUS details. Please could you give this a try?

Thanks,

John

Hi John

Did it ask you to enter any username and password details when you connected the new router?

Re: RADIUS Authentication Problem

JThornton — Mon, 27 Mar 2023 08:51:56 GMT

Hello,

No, it used the default credentials already set up in the router.

Sorry we posted at the same time. Could you try adding the details for username and password.

I've had another customer with a very similar issue and this resolved it.

Re: RADIUS Authentication Problem

JThornton — Mon, 27 Mar 2023 09:27:46 GMT

I've tried those credentials and the router will not connect. Here's the relevant line from its log:

PPPoE connection could not be established. Login failed but there was no detailed information delivered by the radius server
