Intermittent connection issues loading/changing site- secure connection failed/site can't be reached

EDIflyer

Is anyone else occasionally getting a 'connection down' error from Chrome (or 'Secure Connection Failed' from Firefox) when changing page - if I hit refresh it works fine. At first I wondered if it was the site I was using but have noticed it on multiple different major websites over the past couple of months and not noticed it from other locations where I don't use Three Broadband so does seem to be related to the router/connection (this is via wired Ethernet too, so not a WiFi problem).  I've tried changing DNS server in case that helps but no difference.

It mainly seems to happen when trying to first load a site or (annoyingly) at checkout when a different site is being loaded as part of the checkout process.  It certainly doesn't happen everytime but does happen with reasonable frequency.  I've also noticed I often get it when trying to pull/push from/to Github too and have to do so a number of times for it to work (browsing the Github website works fine).

 
I'm using a NR5103E with Firmware Version V1.00(ACBJ.0)b14 - I tried rebooting it but to no effect.

I am currently with iD Mobile because they were cheaper than Three with no yearly rises but have the same pros and cons included which is to say:

  • Fastest broadband speed in my area (Same as Three)
  • Cheapest broadband available in my area (Cheaper than Three even when adding the cost of a used 5G router)
    - Technically they offer a SIM only deal, not broadband, so you need a 5G router or tethering device
  • Same Three networking issues even with the iD Mobile's APN


There may be some SIM-only deal websites that can also offer you some additional savings that may be of interest and iD Mobile does offer a rolling monthly contract

Completely agree over the silence from Three, just some acknolwedgement would have made it a little more bearable, but it is what it is..
That said, I was literally on the Smarty website the other day about to sign up (I know, shares network infrastructure with 3, but I recall reading here that these problems didn't exist there, and figured I'd try a month and see), and I thought I'd re-enable 5G mode on the router and see how bad it still was.. Everyone else is away & out of the house this week, so wouldn't have to answer to non-working banking sites, Netflix not logging in, games erroring out etc..
Anyway, it's been 36hours now, and everything is working as it should be.. Gmail isn't erroring out every time I refresh, various sites & apps that were hit and miss working fine, both on computers over wired & wifi connections, and also iPhone over wifi and directly with 5g.. Everything that was broken, or was intermittent, isn't broken this last 36 hours.. I'm still connected to the same cell-mast radios, same bands (though I've changed it to use Band 1 + n78 instead of Band 1+3 + n78 as just using Band 1 for the 4g uplink reduces the latency to 20ms from 30-35ms or so)..
I'm inevitably going to jinx it by posting here, but so far, so good.. Only downside is I no longer get ~900Mbps down, max is now ~500Mbps, but that's fair enough I guess and fine for now..
I'll update if this stops being the case and things go wrong again..

When I went through the various Three MVNOs I did experience the same issues on all of them however, as we are all aware, the issues vary significantly in frequency

I am quite interested in your current results that seem to be caused by the manual band selection as I have not fully tested that under the various APNs. I will have to do that as I only touch the band settings when there are random signalling issues but that is fortunately rare and easily fixed

Thank you for your message and update!

Just to add, still working fine as of this morning, and that the band selection makes no difference and don't think that's the cause and didn't mean to imply that.. When I first re-enabled 5g it was running in auto band selection mode for hours and working fine before I changed it to get the reduced latency..

I have just done a series of checks using some of the usual trigger websites and https://mynoise.net/ gave the usual issue on both iD and Smarty's respective APNs needing two refreshes to actually load the page properly

Unfortunately only Band B3 has been available rather than the usual B1 and B3 with n78 therefore I will need to revisit this at another time

If it is still working for you then it may work for others

If issue appears to be gone for you, would recommend sharing what town you're from.  As someone if turns out to be local, would be an interesting test if they brought their router to the same mast with laptop to see if issue roams between masts (or even just a test of their sim in phone, as IIRC its not exclusive to just routers?)

This is a check-in and a reminder to keep checking your broadband options

There have been no significant changes for myself

(This is yet another prompt for one of Three's staff members of any kind to mention a brief update, even if it's a "There are no changes" message)

To inform you all because it is nested, there has been an update
(You can put those pitchforks down for now but you may wish to use them for decorations tomorrow 👻

Thanks for linking this @Nameless. Okay I'll relent on this point. I don't personally like "no news" updates, but this issue has continued for an unprecedented time, so I'll commit to more regular posts on the thread until this is solved.

Whether there's news or not, I'll let you all know on Monday either way, and continue to update at least once a week.

Thank you for your reconsideration - Please understand that from our side as customers, having a regular update, even if there are no changes, is always better than having no update whatsoever as the former shows interest and implies that the issue is being looked at as an active case whereas the latter shows ignorance and implies that the issue is being ignored, even if that is unintentional...


Thank you for your update and we look forward to the next update
