I've been having an issue with my wireless setup as well. Here's what I'm seeing and what I think is going on. I have successfully connected my printer wirelessly to my router. I successfully connected one laptop (Win 8.1) and I have been unsuccessful in connecting another laptop (also Win 8.1). The laptop that successfully connects is a Surface Pro 2 that supports both 5 GHZ and 2.4 GHZ. My default is to connect via 5 GHZ. The laptop that won't connect to the printer only connects via 2.4 GHZ. I tried connecting my Surface Pro 2 via the 2.4 GHZ connection and I cannot connect to the printer.
The printer output the printer config setup settings and it says it's connected to my 2.4GHZ connection. But I think that is false. When I go into the router, the MAC address shows up in the 5 GHZ section. I'm assuming, given my PC results stated above, that the printer connects to the 5 GHZ connection and only successfully connects to other devices also connecting to the 5 GHZ connection. Is that normal? Are devices only able to see and interact with other devices connected to the same radio (e.g. 5 GHZ or 2.4 GHZ) or should all devices that connect be able to see/talk to all other devices connected on the same router regardless of which radio they connect to? Is there a router setting(s) that plays into this?
Any help is appreciated.
I will try to provide as much info as possible regarding my printer and router:
•What Hardware version is your router? DIR-826L A1
•Link>What Firmware version is currently loaded? 1.02
•What region are you located? NA (US)
•Are you wired or wireless connected to the router? Wireless
•Has a Factory Reset been performed? Yes.
•Was a Factory Reset performed before and after any firmware updates then set up from scratch? Not sure
Does the printer have a LAN wired connection? Wireless? USB? wifi and USB
What wireless modes does the printer support? A, B, G? As far as I can tell it's only N?
What wireless security modes does the printer support? WPA or WPA2? TPIK or TPIK and AES? not sure...but it currently connects via WPA2-PSK

Update: So I changed the settings (can't remember which screen) to disable "WLAN Partition" and this did the trick. Now both laptops can see the printer regardless of which radio they connect to. Can someone explain what each "WLAN Partition" option means though? There is a separate checkbox for both the 2.4 GHZ and the 5.0 GHZ sections. If I leave one of them checked but the other one not checked, what is the difference between checking only 1 of the 2 boxes, vs. checking both boxes?
