ISP Reviews by Jake

Good value, fast, fixed IP included (single IPv4 and IPv6 range), "use your own router" a selectable option. Can request an increase *and a* decrease in speed up to 1Gb at minimal cost without starting a new contract. Cancellation fees also appear reasonable, not that we have needed to do this! Support is quick to respond to queries - though my IPv6 questions were given terse (but correct) answers. Zero down time in 6 months - a breath of fresh air after the incompetence and dishonesty of "main stream" ISPs. Highly recommended - oh, I'm an IT professional, so really, they are good.

Moved to Origin from Plusnet, as it was much cheaper.
Paid up-front for 18 months 80/20 unlimited, with £1.49 extra PM for a fixed IP, also £38.50 cashback from Quidco.

1) After sign-up, received the expected welcome email
2) Plusnet wrote to give me a switch-over date
3) Origin sent a reasonable Asus router to me, pre-programmed with the PPPoE username. Inside the box was the username and password on a sticky label, but no other documentation.
4) 8am on switch-over day, I plugged in the Asus router. Very pleased to see that the internet appeared to work.
5) That evening, replaced the Asus router with my Draytek router, and found that I was sharing an IP with other users, and could not SSH back in to my home network - this is exactly the same bug described in chaser2001's review.
6) I had a terrible experience waiting for support on the phone; half an hour waiting for 1st line support, then an hour waiting for level 2, at which point I gave up.
7) To get the problem resolved, I messaged Origins social media accounts with a long fault description.
After two days, they fixed the issue and emailed me.
8) Again, as described by chaser2001, I had a few days of routing problems - iplayer was not accessible. I worked around this using a VPN, Thankfully the problem was fixed without me needing to contact support.
9) I still can't login to the Origin customer portal - the password reset page appears to work, except that after setting a new password, it then gets rejected.
Not sure what is on the Customer Portal - so don't know what I am missing!
10) Speed is fine - almost as good as Plusnet. Ookla over the past few days has consistently hit 32Mbs/18Mbs/18ms with a VDSL2 of 79751Kbps/19999Kbps.

Overall:
It's a shame that Origin didn't set things up right to begin with, and their support really needs to improve. However now it's working, I'm a very happy bunny. Fingers crossed it's keeps working...!

If your tech savy, and don't get too stressed waiting on the phone, I'd say go for it...
