For the first few weeks, it worked great, giving me speeds up to 120mbps, which is what I have with Comcast. But now, the speed slows down and I have to reboot to regain speed. This happens every few hours.
- I am on Comcast, and I have verified that by connecting my laptop directly to my cable modem that it is still fast, even when the router is slow.
- I have connected straight into the network cable into the router, and it is also slow when the wifi is slow.
- I am using various speed test services and when it is slow, it could be as slow as 10mbps to 30mbps. Sometimes, it even drops connections.
- I have tried upgrading to the latest firmware, downgrading it to 1.0.3.*, and also factory resetting. At first, it's fine, but then after some time, the speed issues come back.
- After I reboot the router it is also okay for some time (a few hours), but the speed issues come back after that.
- I use the Ubee modem that comes with my Comcast plan. But again, I don't think the modem is the issue as connecting straight into it is fast.
Here is the log from the past day:
