Help HELP! My HTC Desire 826 won't connect to WIFI

[Mehr_k]

Hey,
I got the HTC desire 826 a couple of weeks back and updated it to the latest version of android. After the software update, it stopped connecting to my home Wifi. It'd either say "Disabled" or "Connection Error". I did a factory reset and it started to work fine (for about a week). Last night after the battery died, I plugged it in for the night as usual and upon turning it on this morning, the same problem appeared. It won't connect and I've done all the basic things I've tried rebooting it, turning on aeroplane mode, resetting my wifi settings etc. I love the phone but I can't keep resetting it very week.
Is it some software issue with this model specifically? Why does this problem keep recurring? How should I fix it? Guys, I really need Help Please and Thank you

Have you reset / rebooted the router itself?

Hey Danny, Yes I have and it didn't work. Doesn't seems like the problem is with the router since it's connecting smoothly with all the other phones and tabs in the house. It's just my HTC that keeps having this problem.

Have you tried logging out of your wifi on the other devices? That may be too much at once for the router to handle.
