Three Home Broadband: Zyxel NR5103E drops connection and WILL NOT RECONNECT AUTOMATICALLY

[456]

Extremely frustrating - every time it rains, the router drops connection and DOES NOT RECONNECT automatically. It has to be rebooted manually, which you can only do from home.

If you're away from home and rely on your home broadband to monitor your home and your pets, you're screwed. This needs to be fixed ASAP.

Sadly no. Three are useless and don't care. The router - sadly u have to reboot yourself to get it connected again.

This is why I going to stick with 4G (vodafone) as it seem more stable than three 5G. I am getting 144Meg down and 68Meg up all day without issues.

@JonathanB Can we please get an update? This is not an isolated incident. Not only did your 2nd line tech team not fix the issue, but they also decimated my broadband download speed.

This has NOT been resolved. Can we please get an update on this? Thanks!

Hi @456,

I'm sorry for the delay in responding, I had a number of messages build up over the bank holiday weekend.

I have passed on the information to testing teams, but I'm still awaiting feedback from them. I appreciate this is causing you a lot of disruption on a regular basis. Hopefully the team I fed this onto can establish some sort of fix for the disconnection issue, but if it is down to something in the firmware, this can take some time to find the root cause and resolve.

I'll reply on your private message now, so that you can be put in touch with a complaint handling team that has access to your Broadband account, and they can also raise this with a Technical team that can look into your coverage and if there's any issues with local masts that may be contributing to this.

Thanks,
Jonathan

I'm really frustrated at this point. The issue has not been resolved and whatever your 2nd line team did, made our broadband 5 times SLOWER. Yes, 5 times. We used to get 500-600 megs, now we get 120.

Hi, I'm also having the same issue including the drop in connection speed after talking with a level 2 agent that told me that he has "refreshed the settings".

Because of this i have a second try and asked the new level 2 support to revert any changes the previous guy did. After confirm to me that he has roll it back, i did a test and at least i got back my 600+ connection speed.

I asked him what he has done because I was clearly able to see that there was cap/shaping on my connection, and his replay was "I have done only set the router on hexadecimal address and that is for the 128 bit that is the reason you are getting best speed now." (a fancy way to say i enable IPV6)

I challenge that because before talking to him today i did a factory reset on the modem and the speed were still the same. Also, i has never received IPV6 on my router even if i force it to do so now. So, the configuration he did was not in the router but at the system level.

hope this give you an idea may be talk to a level 2 support again and ask them to re enable it (if it is the same for you) and see if that also fix it for you.

Hi there! Thanks so much for letting me know about this. So, what was it that was changed, in the end? Do we know?

[devaraja]

The quick answered would be to ask them to re enable ipv6. if you want to use the same words, they told me then you can ask them to re enable "hexadecimal address".

I hope this helps.

[456]

Thank you SO MUCH! That finally worked and my speeds are back to normal - from 100meg to 500+meg now. I really appreciate your help. 🙏

Hi @456,

I can only read between the lines here, but it sounds like the 2nd line team set both your and @devaraja's APN profile for 3internet on our system to an IPv4 only version, and it's had an unintended consequence on speeds.

I suspect you could confirm this by setting a manual APN and entering three.co.uk instead of 3internet. If the speeds go back to normal, then that proves there won't be an issue with the network or the router causing this.

three.co.uk is primarily intended for phones though, so it may not work with all your devices. Once you've performed that test, it'd be best to switch back to 3internet, and as @devaraja suggested speak to the team and ask to be put back onto the IPv4 + IPv6 APN profile.

Thanks,
Jonathan
