N600 C3700 Wifi Speeds Slow
I have an N600 C3700 cable modem/wifi router, and I am having trouble with the speed of my wifi connection. I have Comcast Blast 150Mbps service, and my wired connection typically gets 175-180Mbps (testing with both Speedtest.net and Xfinity's speed test site). However when on wifi I typically am getting 25-30Mbps on the 2.4GHz channel and maybe up to 50Mbps on the 5GHz channel. I’ve tried on two different android phones, two ipads, and a macbook air, and all have those same slow results over wifi. Tested when within about 3 feet of the router, all the way to 20 feet away. I have run the tests dozens of times over the past several days and those results are consistent. I have checked all the settings on the router and all appear to be per Netgear recommendations. I am using WPA2-PSK [AES] security and both 2.4GHz and 5GHz are set to the “Up to 300 Mbps” mode (I understand I'm not going to get 150 Mbps on 2.4 GHz, but I think I should get it on the 5 GHz). There are no neighboring wifi signals on the channels I am using so it is not an interference issue, nor are there any other possible interference signals in my home that I am aware of. I have tried disabling the encryption and still get the same speed. This morning I did a factory reset and confirmed I’m on the latest firmware (v2.02.06) and I still have the same problem. Any guidance on how to increase the wifi speed?Netgear C3700 on COMCAST - Please don't buy it !!
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 !
Internet lights out, no US, slow DS
I have a CM3700. Everything was working fine for a few months. Yesterday I lost internet access. I checked my router and the internet light is out and the DS light is slow flashing, no US. The ISP insists the problem is with my router. I plugged my Ethernet from my router to my laptop and logged into the router and it says no internet access please check RF connection. Any help would be greatly appreciated.Takes long to connect to Internet after restart and slow speed
Hi All, Lately i am experiencing slowness with internet speed with NETGEAR N600 (8x4) WiFi DOCSIS 3.0 Cable Modem Router (C3700). I have 50MBPS connection from Comcast. I get around 2 MBps speed. Comcast customer care asked me restart the device. Every time i restart, this router takes 30-40 min to connect to Internet. Comcast told its issue with the router. After 40 min it works fine for 3-4 hr. Again i see slowness with internet speed. Comcast is not able to debug issue due to time it takes to reboot or reset. What can be the issue?embedded web interface fails after week runtime
Have C3700-100NAS, currently running firmware V2.02.08 upgraded thru Comcast xFinity ISP. Can normally connect to unit's embedded web interface both thru default IP 192.168.0.1 and URL http://routerlogin.net no problem...for about week after bootup. After running seemingly normally for few days to week or so, can no longer connect to web interface neither thru either 2.4Ghz or 5Ghz WiFi frequencies nor Ethernet cable -- LAN clients do still have good internet connection, so appears unit's cable modem WAN connection as well as router LAN connection are operating normally and only web interface has failed. When web interface fails, only solution is to power-cycle unit, which seems to restore ability to connect to web interface (for about another week) then web interface fails again. Any insight as to how to fix this problem would be appreciated.Can't connect to cable modem/router; Can't access router login
so... i've been searching around and trying ideas for three hours now. nothing. after a reset, my laptop can connect to the router AND use the internet via WiFi. i was able to use the "routerlogin.net" app once or twice to change my settings back to the way they were, yet no other device would connect and it would tell me the "modem is offline". consistantly, less said times, the router will reset, my laptop will connect with default router settings, my laptop will get internet, and i will get the message that i am not connected via WiFi when attempting to access "routerlogin.net". what the heck is going on here?Open/Close ports when I want
I'm trying to open/close ports when I want for testing purposes. I have the C3700 router. For example when I use http://www.yougetsignal.com/tools/open-ports/ and search for port 2000, it is closed. How do I open it? I tried in the settings, but no luck, hopefully someone can help me! :)C3700-100NAS signal strength
I've noticed a significant decrease in signal strength within my new home to the point where I cannot even connect from the floor upstairs on the other side of my home. Total square footage of my home across 3 floors is only 1,576 sq ft. We had an acceptable signal when we first moved in but it has been slowly getting worse. I've already moved my router as far as I can but it still resides primarily on one side of our second floor within our townhome. This is also where the cable connection is, I'm unable to move it anywhere else. I'm looking for ideas to potentially help boost the signal, neither 2.4 or 5.0 GHz will connect. There was an article about trying to use another router as a repeater (http://kb.netgear.com/app/answers/detail/a_id/20604/related/1). Unfortunately when I go into the admin panel of my router (C3700|N600) there is no "wireless repeating function" under the advanced wireless settings.
