ASUS RT-A68R Router running SLOW
Just a note in case you are having a similar issue. Upon logging into my RT-A68R router for a check up, I noticed a red exclamation point in a yellow square, telling me that a firmware update was available. Always concerned about keeping software up to date, I did the update.
About a week later, I realized that my computer was running very slowly on web pages. I connected the computer directly to the Comcast cable modem and it ran fine. Back through the router, not so much. Things were also fine on WI-FI, but the Ethernet connections were poor. This was getting to be quite evasive until I put 2+2 together about the update. With Comcast, support comes from the Philippines, so not much help there for complicated problems.
ASUS newest update is #4164. The previous update is #3831 and it too runs very slow. I went back further and downloaded and installed #3264, which works much better!
Now I have a sooper-dooper Netgear Nighthawk X6 AC3200 aka R8000-100NAS router to either return to the store or put to work. I'm not sure whether to install it or not, but I'm tired of messing with stuff that doesn't work correctly. Preferences? ASUS? Netgear? Linksys? Belkin? (Belkin now owns Linksys - no longer Cisco and not so great customer service.) The only way you can troubleshoot this stuff is by having duplicates!
