Hub one 5ghz not working

[#1]

Hi,  had an issue which has suddenly got worse. Split bands for 2.4ghz and 5ghz with the same password. Has always asked for passwords repeatedly for the 5ghz band. Or would work after a reset. But this cannot be accessed at all. Changed the password etc etc. 
I think it’s a firmware issue, after reading some other posts...? We are using 4.7.5.1.83.8.259. Think this is quite old now. We’ve been with plus net a few years. Speed seems to have dropped off a little with regards to reliability of the speed too.

Is there anything I can do? Or push an update? 

Please and thanks 🙏

That's what my recently-supplied Hub One says. I run it similarly to you, separate SSIDs for the two bands, but the same password. No issues.

@Nimmy - That firmware version suffers from a known bug that causes exactly the sort of problem you're describing. Somewhere along the line, your hub must have fallen off the management platform because otherwise it would have been updated to run the version @HPsauce has.

Unfortunately, your firmware version is also old enough that it's no longer possible to update it remotely, so instead I'll arrange to get a replacement hub to you.

I hope it resolves your issues.

@bobpullen @HPsauce Thanks very much. I've just had confirmation that a Hub Two has been ordered.

Is it still possible to split the bands on this?

Thanks

@Nimmy I don't think Hub two is as amenable as Hub one on this, one reason I'm happy to stick with Hub one..

@Nimmy - I'm afraid not. Sorry, should have called that out. Hopefully it won't be the cause of too many problems for you. Let us know how you get on.

@bobpullen @HPsauce , no worries. Will let you know if I have any issues. Many thanks for the speedy help
