Hello,
I have been having significant performance issues lately with my internet throughout the house, both wireless and wired. I finally contacted my ISP, after seeing random "[DoS Attack]" listings in the logs and realizing they often coincide with complete disconnection from the internet. (My issue is both slow internet and at times, no internet.) The tech assured me nothing looks wrong on their end, and the DoS Attacks weren't something to be worried about.
That's fine, but nothing has improved for me, and I've noticed an increase in them now. I hope someone in the community can point me to a solution. Thank you in advance!
Below is what I hope is all relavent information:
Hardware Version: 3.0
Firmare Version: 1.02.21
