REDUCED WIFI SPEED with NETGEAR R7500

I am having troubles with my NETGEAR R7500. I upgraded to 110mps speed by am only getting speeds of around 54mps.

 

 

  • Hi Duckdive,

     

    This is weird as other devices connected to the R7500 via ethernet does no have this issue and only this computer. Please try to update the driver of the LAN adapter.

  • What kind of device are you using?  Smartphone?  Computer?  If it's a computer, what is the model # of the Wi-Fi adapter?

      I have Wide Open West internet with 110mpbs

       

      My lap top has Qualcomm Atheros AR956x wireless adapter. When i connect using cat5 cable i get extemely high speeds on test but i keep dropping off interent. As for the two computers, they have USB Realtek RTL8192CU 802.11N adapters.

       

      Thank you for your assistance.

        It's hard to find information about the Atheros AR956x, but it appears to be a single band (2.4 GHz only), single stream 802.11n Wi-Fi adapter.  When using 20 MHz wide channels (very common with 2.4 GHz Wi-Fi when other Wi-Fi networks are present), the maximum link speed possible is 72.2 Mbps.  Real world throughput will probably be in the 25 to 35 Mbps range.  If no other Wi-Fi networks are present, then you may be able to use 40 MHz channels and a link speed of 150 Mbps.  Real world throughput will be 50% of that or less (75 Mbps or less).  But I wouldn't count on being able to use 40 MHz channels with 2.4 GHz Wi-Fi.

         

        The Realtek RTL8192CU adapters are dual band (2.4 GHz and 5 GHz), dual stream 802.11n Wi-Fi adapters.  These should be able to connect at a link speed of 300 Mbps at 5 GHz.  Again, real world throughput will be 50% or less (150 Mbps or less).

         

        With respect to the R7500, you will want to make sure that WMM is enabled.  Without it, Wi-Fi will slow to a crawl.  The other QoS functions, like upstream and downstream QoS, can remain off.  Since you have pretty fast Internet service (120 Mbps), you probably won't benefit from QoS, so I recommend that you leave upstream and downstream QoS off, but feel free to experiment.

  • I'm not sure if upgrading the computer will net you any additional speed. The Realtek's should be capable of saturating your 110 Mbps Internet connection. Your laptop will definitely benefit from an upgrade. Upgrading to an AC1200 adapter will leave you well positioned to take advantage of any future speed increases to your Internet connection. It will also help with local file transfers between your laptop and other local devices.

    As for your Internet connection, more information is needed to diagnose it. You may need to log into your router as well as your modem and do some sleuthing. Is the connection dropping from the router or is the modem also losing the connection? Look at the logs of both devices and look for signs of the Internet connection dropping. There might be a reason given.

    You may also want to try a different Ethernet cable. It could be bad. Also try a different LAN port on the router.

      My wireless speeds are UP! My only problem is when i am wired directly from my laptop to the router my connection drops every few minutes. I have to unplug the cat5 cable from my laptop and then plug back in. Any suggestions for this?

      Thank you,

        Hi Duckdive,


        Welcome to Community!

         

        To isolate the problem, connect a different computer wired to the router and check if it has the same problem. Try all ports of the router and use a different cable. If it only happens on one computer, you may need to update the LAN card of that computer.
