Windows 10: Router Internet VERY SLOW!!!

    Router is broadcasting a very weak signal


    I posted this in the Network forum - but did not receive a good response. Hope it's OK to post it here for a better response. I use COX Cable and pay for 100Gbps. That speed arrives at the modem (the router is separate as of now). When my computer is only three feet from the router, I can only get about 15 Mbps. My COX specialist spent almost two full days trouble shooting this issue. He changed the router/modem five times (brand new right out of the box) and got the same poor results. He did a great job in troubleshooting - but with no success. No one in my neighborhood uses HAM radio. Something is squashing the router signal but we can't find the source. The COX tech went way over the line in what COX is responsible for - but finally gave up. He told me COX Cable is only really responsible for getting the signal (100Mbps) to the router - which it does. He said no ISP is responsible for the signal coming out of the router. So, I'm on my own. Hence this plea for some ideas on how to fix this problem. I should also note that hard-wired, I get a great signal to my computer. Hopefully, someone in this Forum can help me out. Thank you in advance!!!

    Well if you get a good speed via ethernet, then issue has nothing to do with ISP. You say a good signal - do you mean good speed?

    If that is the case, issue lies with wifi drivers somewhere.

    Sorry, I neglected to mention that we also tried four computers (two Apple tablets and two Windows 10) - same result.

    This may seem wacky, Nisko, but I imagine that, if it was happening to me, I would shut off every circuit breaker in the house except the circuit powering the modem & router & computer (and have nothing else on the circuit) to see if I could rule out some device in the house "squashing" the signal.

    You live in USA? I read somewhere, that it has only 3 allowed WiFi channels, so maybe it is overcrowded.
    Check out, what channels are used by other people and their strength and try to set the one used the least.
    Also try to use 2,4GHz, if possible, it is actually stronger and less used, since everyone uses the latest 5GHz.

    WifiInfoView - WiFi Scanner for Windows 10/7/8/Vista

    P.S.: It might be worth trying to disable IPv6, it only causes problems, especially on WiFi.

    Clearly your problem is with the Wireless Access Point. No idea where it would be in yours, probably the Router/WAP.

    1) Check the aerial(s) connections, are they plugged in properly. More difficult with boxes with internal aerials.

    2) The Wireless Access Point maybe faulty in some other way and only operating at low power. Check settings.

    3) The WAP maybe old and only to Wireless G specs which only operates at 2.4 GHz. That has a limit of about 15 Mbs in practice.

    4) If the WAP is actually dual band(2.4 GHz + 5 GHz), is this switched on and being used ? Settings again.

    You may need to update your Wireless Access Point(Router hardware) to one with hardware to Wireless ac standard(5 GHz), these are backwards compatible to Wireless G (2.4 GHz) and so on.

    You may also have to check the specs of the Wireless Cards of your devices.
    For example a single band b/g/n Wireless Card in older Laptops would not be able to get up to 100 Mbs, maybe around 60 Mbs or something like that.

    A new Router/WAP to the new Wireless ac standard does not cost much, so just getting one and using it may prove a point quite easily.

    @Word Man : I think it's a great idea. I'll give it a try. @TairikuOkami : I am on an uncrowded channel. How do I use WiFiInfoView? How do I disable IPv6 - and what does it do? Also, what happens when I disable it?
    @Helmut : My router is brand new and AC compatible. I am getting a new network card for my computer which will accommodate AC - but I have the same slow signal on all my computers.

    TO all: Should I change my DNS server? If so, which is the best one?

    I use inSSIDer Home to determine which channel I should be on - both 2.4GHz and 5.0GHz.

    DNS server is nothing to do with this.

    Interfering sources, like certain types of intruder/burglar alarms operating in the 2.4 GHz band can be a problem.

    Do a survey of Connection speeds and actual speeds on each Device(you say 4) you connect to the Wireless Access Point. For both frequency bands.

    Out of those 16 results something should emerge.

    Most of what is in #6 also applies to new hardware as much as old.

    Thank you, @Helmut. What is the difference between connection speed and actual speed?

    We need to be clear you would your paying for 100gb connections no way on earth is that correct Cox have only just rolled out 1gb. If you haven't yet got the new AC router the max speed via ethernet is 100 meg as that's all the old router is capable of via cable. There will be a massive MTU difference between router and modem on YouTube there only getting half speeds from Cox Gigabit internet over coax with Cox Gigablast! 1000mbps copper! - YouTube
