Is this important or can you skip it?

Thanks ATLga. My Google search did not show anything...!

FYI, I installed the 20253 update on my Asus RT-AC1900p the other day. Suddenly CPU overhead is off the charts. Both cores consistently run 95-98% when the router isn't doing anything at all (compared to 2-5% normally). Needless to say, everything (including the stock router interface) is very laggy with that update. A factory reset only cured the problem for a few hours. I downgraded to 20252 and problem disappeared. Tried updating again...same scenario. So I've put 20252 back on until Asus can fix the update.

After updating my Asus RT-AC68P's stock firmware to 3.0.0.4.385_20253, I am experiencing the same issue--my router's CPU (both cores) are consistently running at 85-95% and the (router's) WebUI is extremely sluggish. In an attempt to resolve these issues, I restored the router to its Factory Default settings, and reconfigured the router from scratch, but the performance issues returned a couple of days later; to my dismay, the router had been working well--the CPU's cores were running between 0-30% for a couple of days--until the problem resurfaced.

After reading forum posts last night about reverting the router's firmware back to firmware version 20252 to resolve these issues, I became extremely hopeful that I could return the routers performance back to normal, but unfortunately, I am unable to revert back to 20252. Following Asus' instructions, I restarted the router in Recovery Mode and attempted to push firmware version 20252 with the Asus Recovery utility, but the process fails at around 87% of the firmware push (consistently). The only thing I have plugged into my router is my PC (into LAN port 1) and the router's power brick.

With that said, I was wondering how you reverted back to firmware version 20252. Any suggestions? Thank you for your time, I really appreciate it.

I went to the ASUS website, and under products chose networking/wireless routers. Choose your router and click on support. You can choose any of the half-dozen or so most recent firmware updates. Download to your PC, then in the routers UI, go to firmware update and choose to download from your pc. Takes about 5 min total. There’s clearly a bug in 20253. It was designed to address the Kr00k vulnerability...but they must not have tested it properly.

10-4. Thank you. I originally was going to attempt the firmware update there, but was concerned that the Firmware Check and Manual Update (AiMesh Router) sections were separated. I wasn't sure if the AiMesh section referred to the router's firmware or an alternative mode that I was not running, but after your feedback, the feedback of other forum members, and digging a little deeper in my router settings, I see that I overlooked that the router is branded as an AiMesh Router (I have had the router for 4-5 years and never really noticed this and have never had any problems until now). I apologize for the dumb question (I'd be the first to admit that I am no expert when it comes to this device), but your feedback helps immensely. I will try the revert back today. Thank you so much! I hope you have a wonderful day.

My apologies, I'm a member to SNB Forums and these were my first posts. Rookie mistake--won't happen again. Thank you for your feedback.
