Router denying Wi-Fi access?

[Shandy]

Hi.
 I'm having a little trouble with my router accepting Wi-Fi connected clients at the moment and I'm not sure what is causing the issue.
I don't recall recently changing any settings for my router related specifically to Wi-Fi and it accepts physical connections fine. The only change I made recently is to provide IP address reservation for my main desktop on the network, however, my Wi-Fi devices still worked fine after this for a while.

The router is a TP-Link WR2543ND.

When Wi-Fi devices try and connect I get traffic reports like this:
ID   MAC Address   Current Status            Received Packets   Sent Packets   Configure
1   5C-95-AE-01-E0-08   STA-ASSOC     333                          2

It looks like my devices are sending multiple handshake requests but the router is not responding. Sent packets from the router will remain on 2 or 3 with the received packets increasing over time. Does anyone have a clue to what might be causing this issue, and is there any way to pull a report from this model of router of all the current settings and statistics so that I can share them to locate errors?

Many thanks.

I didnt read it all, but im sure the answer is here...

Did you possibly turn the 5ghz band on? When I did that with my router, the 2.5ghz stopped working and devices didnt use 5ghz correctly... maybe check that.

Thanks for the reply Kyle, yeah my router only supports singular band transmission as well and that was the first thing I checked. Definitely on 2.4Ghz and also has 802.11 b/g/n protocols enabled. I looked through the manual but found nothing useful. Also I can't find any results on Google of people experiencing similar issues, pretty strange.

I guess I'll have to restore to factory settings and lose all my forwarding/routing settings etc.

Thanks.

I've resolved this issue now.

I was looking through my router settings again and saw that DHCP service was disabled. Without this my Wi-Fi devices can't be automatically assigned an IP address. It's not something that I would ever normally disable so must have switched it off by accident. There is probably a lesson to be learned here somewhere. 

Thanks again.
