Well I tried Netgear Support and they were zero help....I have the C3700 - 100NASEverything worked fine for a couple of months but now nothing except my 2 computers connect and works like normal with the router.My cellphone, printer and TV all say they are connected to the router and when I log on to the Genie it also says they are all connected.However the internet/apps load incredibly slow or don't load on my cellphone. The printer keeps saying it loses connection to the computer and the TV won't load Netflix or anything else. If i reset the router everything will work fine...for about 2 minutes. I've tried resetting and there is no signal interference. I cant seem to figure out why my computers work fine but nothing else does...any ideas?

Not a happy customer...You all are correct. Netgear support is useless. I've had nothing but problems with the C3700. I have the same problem as many of you. My problem seems to be with 5G on the C3700. But there appears to be no way to turn off 5G signal even though manual shows screenshot where you should be able to turn it off. My screen looks the same but without the option to turn off 5G. I've rebooted this modem more times in the few months I've had it than I ever did with my other netgear modems in the last 10 years. Lately, Comcast even told me that the problem looked to be the modem.Second problem...The updates page had a VPN hotfix. Ran the hotfix and got an error. Phone support wouldn't support it because I'm just past the 90-days of the free useless support. I've also seen something on the Netgear site where the C3700 doesn't supposedly support the hotfix, so why is it on the update page for the C3700?I can now understand why this modem got only a 1-star rating and didn't even make the list for the best known modem manufacturers. Netgear used to have great products...what happened? Now heading to buy a better brand rated modem for less than what I paid for (what I thought was) a quality Netgear product but actually works better as a paperweight.

Yes, the 90 day support is stupid. I now want to use this readyshare that is required if I want to add an external drive to pull from onto the modem/router, N600 C3700. Can't seem to do anything with it. The manual states how to do it, but nothing stated in the manual is available. I have spent 2 days trying to figure this out to no avail. So seems worthless. I spent all this money for what was at one time considered a very good piece of equipment. I have learned in the last few months I will never buy a netgear anything ever again, and have been busy telling everyone how worthless the company is in support. I know I use to see this external drive when I had it hooked up months ago, but now it is lost in never never land.

If so many customers are having this same problem, why is Netgear not helping us fix it? That seems like the rational thing to do.

I too am having QoS issues....latency and poor bandwidth using c3700 modem & router with Comcast Xfinity....while using wireless and/or wired. Web pages render slowly and Microsoft Lync calls are garbled intermittently. It was working well till a month ago or so; since then performance has degraded intermittently to the point its impacting my productivity. Comcast if of no help, and can't find any support on Netgear. Is this c3700 model a lemon? Or was some firmware pushed down unbeknownst to me that is now mucking things up? Currently v.1.01.11. Tried factory reset to no avail. Any thoughts or suggestions?

I have the same exact problem. Worked fine for a month now, I have no internet access, but I am "connected". Same problem on WiFi and Ethernet.However the guest network wireless LAN works perfect!I noticed the IP range for the guest network starts at 192.168.1.1,0.For the primary LAN IP it starts at 192.168.0.10.Tried resetting the router etc.

I'm having horrible problems too with the c3700. It is a huge racket to extort money from their customers. I have no way to update the firmware, doesn't give that option in the router settings like the help page says. Customer support says it's not a hardware issue, and they an fix it but since I just passed my 90 days I have to pay them. They won't replace the modem until I pay them to TRY to fix it over the phone first. My isp (which is wow) came out and looked at everything and it's clearly a a modem issue. I can't connect on wifi or wired. I went to a coffee shop and downloaded the supposed "fix" and all it does is reboot the router. Phone support told me there was a free chat (lie) or I could find the walk through (which des nothing to help my problem). Only two options are to give them money for a product I ALREADY PAID FOR!!!!!

I'm having same issue, really frustrating. Customer support wants to charge you more than the router costs and says they can fix it! No thanks, I'll buy a new one and it wont be NETGEAR!!!! Worst customer service and clearly this is an issue since so many of us have the same problem.

  I had similar issues, my 2.4g internet and direct lines work, but it seems to only be a 5g issue.
  
  I looked everywhere and couldn't find a fix, so I decided to try it myself.
  
  I cleared all event and access logs on the device, then I use a WiFi analyser to find a better channel and changed the channel to a more clear one.
  
  I then rebooted and now on my tablet and cell phone the 5g works great again. On my wife's inam still having minor issues. Hope this helps some of you.

Tech Support is USELESS! They ran me around, in circles, for 4 days, with no solution.
Does ANYBODY know how to set up a USB printer, with ReadyShare?
