Fast LAN speed/slow WiFi speeds

I sent in a ticket to support on this but still haven't come up with a solution so I thought maybe some forum users might have an idea... I've got the WNDR4300 with the latest firmware. I use an A...

    Doing a factory reset on my router WNDR4300 with latest firmware solved the issue. Now I am able to get 89MBPS on 5g & 75MBPS on 2g. Thanks a lot.

Hello Elaine,

 

I contacted Netgear and the support technician had me changes a few settings using the Netgear Genie. At first the speed was slower when I ran the test using speedtest. The support technician told me was going to check with his collegue and never came back to me or returned my call after an hour. Here's the issue. I am with Xfinity/Comcast. When my new C3000 Netgear Router/Modem is connected with with the wire. The speed is phenomenally fast. I am getting over 90 Mbps consistently. THen when I unplug the wire and go wireless. The speed on IPv4 range between 22 to 29 Mbph, and between 33 to 39 Mbps on IPv6. Those are less than half the speed I get using on the LAN with the wire connected. So I wanted to know if this was normal for the C3000 and for my region. I was told that I should be getting at least half the LAN speed or more by the Netgear support technician. Since that call to Netgear. I have not changed any of the settings, and I am still getting less than half the speed of the LAN on the wireless, even when I take the speed measurement with my PC within arms reach of the Router/Modem. 

 

So if anyone here has had this issue, and managed to find the right settings for increasing the speed of the download to at least half of what I get using the wired connection. It would be greatly appreciated if you would share the information in details. 

 

Thanks

    8Ohms What's the model of the wireless adapter that you're using? Do you have the latest firmware installed on the cable gateway? The latest firmware is 2.02.06.

    Powercycle your cable modem in order to install the latest firmware. If you're still having difficulty getting the latest firmware, contact your ISP.

    Another thing for you to check is interference. Make sure that there are no other devices that may interfere the wireless signal between the wireless router and that computer.

    Have you tried changing channels? What channels have you tried? Avoid devices that may interfere such as cordless phones, baby monitors, microwave ovens, etc.

    If changing channel did not help, try to change Fragmentation Length & CTS/RTS Threshold to 2304. The settings can be seen under Advanced > Advanced Setup > Wireless Settings

    Once you saved the settings, you may have to reconnect your device to the network and observe your connection.

    By the way, have you tried checking the speed on a different computer? If you can it would be great just to isolate the case.

      Has anhyone made progress on this problem? I have the same problem with my C3000 - excellent wired LAN speed, and terrible, unusable, 1 to 2 Mbps wifi download speed. I've tried pretty much everything that's been mentioned in other posts - changing channels, making sure that the firmware is the latest, disabling WMM, making sure that I'm on a channel that nobody else is using. Nothing changes the abysmally slow wifi. It's consistant across multiple machines in multiple locations in the house. It's hard to believe that this is just the way these routers work...

        For what it's worth, I punted and bought a separate wireless router and connected it to my Netgear C3000. Ansolutely nothing I did could raise the WiFi speed of the C3000 above about 1-2mbps max. Mostly it was right around 1mbps. Totally pitiful. And this was consistant using different machines, different locations in the house, disabling WMM, different channels, and channels that didn't conflict with any other signals in the neighborhood. And this is with full 25+mpbs coming in on the cable (our current plan is a 25mbps plan from Comcast/Xfinity). 

         

        So, I bought a separate wireless router (from a different vendor), disabled the WiFi antenna on the C3000, and am now using the C3000 as just a cable modem with the WiFi router connected through the ethernet cable. With the external router we're back up to 25+mbps on WiFi which is the max speed on our current Comcast/Xfinity plan. 

         

        It appears that the antenna and WiFi section on the C3000 is just not up to the task... Humph.

      Elaine,

       

      Thanks very much for your assistance. I have checked and do have the latest firmware. I do not have any adapters. Just the C3000 Router/Modem. I have done my best to make sure the path between the Modem and my computer is clear. I have just the equipment that you would typically find i close proximately of a router in a home or an apartment. As per your suggestion. I change the Fragmentation Length using Netgear Genie. I had 2301 and 2302. I tried the 2304 and changes the channel to one that was less user. The results of the Xfinity speedtest was slower speed. I was getting 20 mbs on the IPv4 and 30 with IPv6. So then I rebooted the modem and returned the Fragmentation to the original figures and the speed went back up to approximately 30 mbps on IPv4 and 40 mbps IPv6. 

       

      No doubt this is very fast. But as I mentioned before. the LAN is returning over 90 to 103 mbps. And all I am trying to do is get the maximum amount of wireless speed out of my new modem. I am unable to try the speed on a different computer. I hope to get at least 50 to 60 mbps if this is possible with this modem. 

       

      Thanks

        8Ohms,

         

        I have exactly the same issue. Cable router C3700 and Comcast provider. On wire I have +120 Mbps but on wireless 2.4G ranges from 2 - 27 Mbps and 5G ranges from 30 - 48 Mbps. I really want to know how to fix it too. My router is still under warranty and I may go change it if this continues as most devices at home only compatible with the 2.4G and the 2.4G sometimes totally drop to no internet.

         

        NetGear Techs,

         

        Please look into this and provide any help you could ASAP.

         

        Thanks Isaac
