Asus Router Connection Problems and Possible Fix

I have an Asus RT-AC3100, but this fix may potentially work on other models.

So the symptoms of the problem I was having included:
  • inconsistent pings or unable to ping another device (sometimes it worked if I tried to ping from one and then the other)
  • Network printing drops off
  • inconsistent network discovery if it works at all
  • high latency for simple local pings (like 9-15ms as opposed to 1ms)
  • network map constantly dropping and adding devices as their activity changed
  • inconsistent snmp, sometimes devices not responding for days (I had a few days when the router showed as down, but all my other devices as up, which is impossible to actually happen)
I searched the internet for days trying to find any hints at this, and it was always the same story, upgrade your firmware. Well, I do. I check at least once a month for updates and update, even if I have to upload it manually. So what is the solution I just found? Well, it's dumb and stupid but it looks like it's working.

Solution:

Go into the LAN option under Advanced Settings. Click on the Route tab. Change Enable static route to yes. Then we add a network to it, I'll assume yours is like mine. Under network/host, add 192.168.1.0. Netmask should be 255.255.255.0. Gateway will be the router ip, 192.168.1.1. I just ignored metric and left the interface on LAN. Click the + and then apply. It took my router a moment after rebooting before it went into full swing, but that could have been in part due to this old mac book pro being a bit weird with the network connection in general.

I hope this helps anyone having these issues.
