[I noticed Larkey has also previously experienced this issue and posted similar steps in another thread, this information really should be in the sticky!!]
Hi All,
The software on the D-Link 882 seems to be especially flaky, I experienced frequent disconnects. I was also unable to connect an Xbox One with the default settings and it stated an error of incorrect wifi password. I finally got one Xbox on with manual port settings only for it to disconnect three days later. Furthermore, port forwarding for my WD Cloud NAS failed to work.
I tried to follow the stickied guide to switch to DD-WRT and it failed several times in a row and took up a lot of my time. I purchased the router in January 2019. After much reading of similar reports, I thought I'd leave the steps I used to fix it here to save you some time. Any steps that aren't clear to you are explained in more detail in the stickied post.
1. Boot into the recovery mode by powering the router on while holding the reset button
2. Set your computer with a wired connection to the router to a static IP - I used 192.168.0.3 (disconnect other hard wired devices).
3. Navigate to 192.168.0.1, Internet Explorer and Edge both failed to work for me, I used Canary - Googles Beta version of Chrome, I imagine Chrome will work fine too.
4. Select the factory to dd-wrt file to flash DO NOT HIT UPLOAD! Hitting upload here crashed the router every time.
5. Leaving the web browser open and the file selected, turn the router off.
6. Turn the router back on whilst holding the reset button to enter recovery mode again.
6. Wait two minutes for the router to boot into recovery mode and then (using the tab you have already opened and selected the file on) hit upload.
7. Leave it to do it's thing for a while and wait for the success page, the router should automatically reboot. If it doesn't, leave it an extra 5 minutes - don't interrupt while flashing!
8. Set your computer to automatically obtain an IP address and it should then allow you to navigate to 192.168.1.1 to access a DD-WRT screen. You can update DD-wrt from the webflash now, I'm using DD-WRT v3.0-r37305 std (10/10/18) and it appears to be stable for me.
I'll describe the issue with the Xbox One in the next post....
