Hi, I'm having problems with my Samsung s7 connecting to my Plusnet hub one router, it has been connecting but now its saying "Authentication error occurred", all my other devices including another Samsung s7 phone are still connecting. Any suggestions to solve this please.
Fixed! Go to the fix.

Welcome to the forums @kaydon69 . I'm no Android (or mobile phone expert), but having done a quick check, this seems to be a common error with Samsung phones, although the links I saw generally referred to the S8 rather than the S7, and the solution I'm going to suggest may not work, but is the easiest.
Try rebooting the offending one when you are at home - completely turn it off, wait a couple of minutes and turn it back on.
What version of operating system is it running?

@kaydon69 I suspect it is because you have two S7 phones, and they are both trying to use the same IP address - which just doesn't work. they have to be unique.
I haven't got much chance of searching for a solution today, but I'll try and have a think sometime tomorrow.
In the meantime, if you have a few spare moments, try Googling that error - you may find something yourself. If all else fails and I can't help you solve it, I'll have to ask someone with more knowledge if they have any ideas.

Sorry @jab1 There's no way that should happen. Even though they are the same make and model , every network device, wired or wireless , has a unique mac address. That mac address is used by the dhcp server in the router when assigning ip addresses. Hence no two devices will be assigned the same ip

@MisterW I agree, but a cursory search mentioned that possibility, albeit for the S8 rather than S7, and I offered it as a possible easy solution for the OP - although it didn't solve the problem, obviously.
Any suggestions, because I'm no expert on this type of problem, especially where Android is concerned - I'm an Apple user.

The only time I've seen anything close to that, was with a pair of cheap bluetooth dongles. Like network devices, they're meant to have unique I'd 's. In this case they were cheap chinese clones and had the same Id.
I cant imagine that could possibly be the case with a genuine samsung phone...

@MisterW TBH, neither can I, but it does sound like something similar is happening for the OP. Off the top of my head, I can't think of an easy way for them to check.

Has one of the phones been updated recently and the other not ?
They're Android phones aren't they , has clearing the cache been tried ? That's always worth a try with Android, doesnt lose any data or configuration.
