c3700 connection issue
Well I tried Netgear Support and they were zero help.... I have the C3700 - 100NAS Everything worked fine for a couple of months but now nothing except my 2 computers connect and works like normal ...
If you go to the Downloads area and search for the C3700 you will see no firmware listed. Netgear provide that router to ISPs, and the ISPs provide the firmware. Netgear cannot provide support for firmware issues if they don’t produce the firmware.
That's funny Andy. I've been dealing with the exact same issues as the other folks on this board for the past two weeks. When I called Comcast and insisted that they push the firmware down as noted on Netgear's site, the response that I received was that Comcast only pushes their firmware to register the modem - not Netgear's. If that's the issue, then why can't we update it manually like other modem/routers??
Having same intermitent issues as described in this thread. I have sent an email to tech support but doesn't sound like I should get my hopes up. I will pass on anything I find out. In the meantime, has anyone had any luck/progress on stabilizing their performance issues? I did a complete factory reset and performance was much better then a regular reboot but within a single day it already froze up and required a reboot.
Hello wil12ken
If you are having intermit internet connections have you checked to see if you have a cable splitter between the the modem and the wall outlet if you do try removing it and go directly to the wall and test to see if your still having intermit connections. The other thing you could try is if you have another active cable outlet in your home is hook the modme up to it and test to see if your having issues. If you find either one of these to fix the problem I would contact your ISP and have them come check the lines. Hope to hear your feedback.

Thanks DarrenM for the thoughts.
I did move cable outlets and the same behavior has persisted. There is only 1 main splitter from the direct cable into my house. I actually have a second modem for work (not netgear/rented from comcast) running off the same splitter and it's does not experience any issues. My work modem is throttle at 5Mpbs and my home connection is 25Mbs. I am not sure that makes a difference.
I've made it a few days with only 1 reset on my home modem. If it doesn't stablize then I think you are correct that my last choice before replacing the Netgear Modem is having Comcast come out to check the line signal strength.
Thanks again.
i have the same issue. i just bought the modem about two wks and now the wifi no woking at at. tried to reset a few times but it still no work. i think about return the product back.
PROBLEM SOLVED !
As you may have seen ive been having alot of issues with this device. The solution is DONT BUY this device if you are with COMCAST !. Here is why:
1. Slow speeds on wifi were due to an out dated firware version on the device according to NETGEAR (Tier 3 agent at the HQ in California)
2. After a FCC complaint that I filed; someone from Corp office at COMCAST called me. HE checked with his senior engineers and said that COMCAST does not have the latest firmware for the netgear device. He accepted that the firmware is completely handled (updated) by COMCAST and not NETGEAR (for the first time)
3. So basically dont use this device on COMCAST and if you want to but your own device in the future please check the compatible device which have been tested and passed with a 3 star rating at COMCAST website. link : http://mydeviceinfo.comcast.net
Make: Netgear Model: C3700-100NAS (Retail) Retail: Yes Device Type: Gateway DOCSIS Version: 3.0 End of Life? No Certification: 
certification should have 3 stars according to COMCAST for that device to have the latest firmware on it !
If you look carefully on this list Netgear device is not properly tested at COMCAST and they will not be doing anything in the near future. However Motorola / ARRIS devices are fuly supported by COMCAST (becasuse they own 10-15% of ARRIS :D )
Sadly ARRIS devices arent the best and their wifi signal strength is absurb compared to some other providers.

I bought a Airport express router for $85 on amazon and this has fixed all my wifi issues. (thank you Apple)
Basically im using a $150 device as just a dumb modem :(
Only if I knew about this corporate mumbo jumbo earlier. God Bless America !
