N300 C3000 Slow Wifi

Okay, so it seems everyone in this forum is having same issue, without solution nor the phone number to Netgear. I am in the same boat as well.

I recently upgraded to Comcast Blast internet service, which provides up to 200mbps. When it is directly connected using wire, it gives full 200mbps.

However, wireless only gives about 1/5 or 40mbps, and after talking to comcast for 3 hours, they said that they couldn't find any problem on their hands, and was told that it must be the modem. I told them that this modem can provide speed up to 300mpbs and thought that they were making an excuse, but after reading posts here, it looks like I am not the alone.

The modem is:

- About 2 years old (no damage at all)

- Directly connected to the wall, no splitter

- Close to my desktop, about 10 feet away 

I tried:

- Modem reset

- Change frequency channels

- Talk to comcast tech support for 3 hours

Any solutions? or can I get phone number to Netgear, please?

Thanks.
