On a wireless laptop we got about 70 on the download and 10 on the upload. So, as far as I am concerned, things are working as advertised. I think this is what finally solved the problem. I contacted Netgear. They had me open a command prompt and run some kind of ping test using changing a channel or mtu size in my wan setup. The default was 1500. At the command prompt, I had to type ping and the number 1500 and I think a space -a and space -f. 4 packets were sent, none received and 4 lost. They had me change that channel/mtu size in the setup for my modem router and run another ping test using that number. Still got 4 packets sent, none received and 4 lost. They had me change the channel/mtu size number again in the router modem wan setup and run another ping test from the command prompt. This time I got 4 packets sent, 4 received and none lost. I ran a speed test and it was still bad. They said to try speed tests after 24-48 hours and if it was still bad to call them back. I ran another speed test after 48 hours and I got the download speeds of 120. So if your having a problem, changing the channel or mtu size (not sure what it was exactly--I think the Netgear rep called it a channel, but it says MTU size when I went back to see what to call it for this post). The Netgear folks gave me the alternate channels/mtu size to try instead of the default 1500. Good luck. Re: 100 Mbps Download, But Not With Cox Nova Server All the lines and splitters in the entire house and to the outside box were replaced yesterday. The speed problem was the same before and after this replacement. A line comes in to the basement and splits, one to the modem/router and on to a TV. What does a service call mean? What does it cost? I have Cox Complete Care. 100 Mbps Download, But Not With Cox Nova Server I have Cox preferred internet with download speeds of 100 Mbps. I got a new modem/router a Netgear AC1900, C7000v2, Nighthawk. It is approved for use by Cox, according to their website. The firmware is V1.02.12, which is also the firmware approved by Cox's website. My desktop is connected to the modem/router with a cat6 ethernet cable. The default internet server that I have to use is Cox Nova. Running a Cox or Ookla speed test on that server I get consistent download speeds of 17-21 Mbps--far below 100 Mpbs I am paying for. If I run a speed test on any other local server, I get consistent download speeds of 117-120 Mbps. If I run a Cox speed test using the Cox Atlanta or Cox Omaha servers, I also get consistent download speeds between 115-120 Mbps, although the ping is 30-40 instead of 7-10. My first call to Cox got me nowhere. What can I do to get the download speed I am paying for? The router can receive fast download speeds, including from other Cox servers, but Cox can't seem to offer a solution to getting that speed from the Cox Nova server, which is the one I have to use. Help! Netgear C3700 Never Worked For Me Just a warning. I could never get the C3700 to work with my PC/Network. Both Network and Cox said it was compatible with Cox. Numerous calls and chats with Netgear and Cox, as well as multiple forum posts and internet searches, resulted in no improvement in stopping the dropped wireless connection issues or my unstable game play. I fiddled with many adjustments. I most recently tried to reserve an IP address and had Cox come out and check the lines. Neither made any difference. I am not PC/Network literate, but I think it might have had something to do with the up channel. The light kept blinking, but both Netgear and Cox said it was not a problem. Cox did say they had had some problems with modem-router combos (he did not single out the C3700). I bought the C3700 at Staples and they won't take it back after 14 days, it was a Christmas present bought 14 days before Christmas, so I have an expensive paper weight. I have gone back and am using my old DOCSIS 2.0 modem and Dlink router and everything is working fine again. Trying to upgrade to Docsis 3.0 has so far been a total waste of time and money. :( Re: netgear c3700 I got a C3700 for xmas. It is on the cox approved list. I have the blinking upstream light and my details from the Netgear Genie are similar to everyone elses. My problem is that devices in the house do lose connectivity from time to time and I have a problem playing a game on an ethernet connection since I got this. I have heard about upstream channel power problems impacting connectivity. I have one splitter, cox says the signal is good. They say power should be 35 to 49 and mine was 51. The genie said the upstream power was around 42 for all 4 channels so I am not really sure if I have an upstream power problem or not. On the ethernet PC, i can watch youtube, or a game, without problem and my connection is always up. When I actually start playing the game, though, I get frequent very quick freezes and lags since I got this modem/router. Not sure if the game and the wifi connection issues are related, but they both happened at the same time. I have seen that an active return amplifier can help solve an upstream power level problem, but I still can't tell if I actually have that problem. Any thoughts?
