I recently updated my DIR-655 (hardware A3) router the latest firmware 1.35NA. After I updated, I noticed that my internet speed was drastically reduced and for some reason, I can't find the set up I had before I upgraded (I had 1.21 before upgrade to 1.35). I've messed with the settings, reset it, did pretty much anything I could think of to get it to go faster.
Last night I somehow made it so no computer but mine would connect to it but I had the speed I wanted. I then reset the router completely and still had the same speeds. It remained fast until about an hour ago when it just bogged right down and I can't get it to be fast again.
I used speedtest.net in order to see what it was doing and I'm getting a download of about .7 every time when I should be getting about 3 with the internet I have. At one point my upload speed was faster than my download which doesn't take a genius to figure out that that's not good.
Any help would be appreciated on figuring out why this update made my internet so slow, I'm assuming something is clicked or not clicked that's not allowing the full speed to be sent out to the computers but I have no clue.
