wifi help :)

  1. i get bad wifi signal upstairs, is there a way to get better signal other then buying a wifi router which i did it helped but it still only gives 50% like my ISP gives me about 125-130mbps down, but with wifi i get like 30-50mbps, anyway to get more? with wifi or is there a device that would allow me to use hard wire rather then WIFI upstairs keep in mind i dont have a long ass ethernet cable to run it from downstairs lol so thought someone might no a device that would allow it to connect ethernet cable upstairs with out running wires all over the place
  2. From my experience the only real way to fix this kind of an issue is through expenditure.
    You can go a cheap route with a Wifi Extenders, however I'm not really keen on these as they're essentially adding another interface between you and the internet, which can potentially raise ping if your extender isn't great.
    You could give in and buy an Ethernet cable and run it to your PC.
    Or you can invest in a more premium Wireless network, this would likely involve a 5GHz frequency from a new router and your Wifi card, though this option is definitely more expensive.

    Unfortunately Wifi is a bit of sticky subject when you want to avoid expenses, 5GHz is also a must-have in your situation as you're going through a ceiling.
    5GHz connections allow for better penetration through walls, whereas 2.4GHz is better for range but sucks for penetrating walls/ceilings.

  3. i looked into some AC routers 100$+ and then i gotta get the 5ghz adapter for my computer and all other devices pretty expensive and that still i do not think would give me 80% of my speed? not sure though. i looked into powerline or w.e if u no of those? what u think about them
  4. That is another issue, to get the rated speed of your connection you very likely will have to spend a lot on a router because for some ungodly reason, decent wifi hardware is never made available to generic consumers.

    If you were to invest in a decent 5GHz Router and a 5GHz receiver for your PC, you could easily get that rated speed.
    As for other devices, my Nexus 4 (pretty old by today's standards) supports 5GHz no problem, so I suspect other devices you have will have no issues.

    Also I wouldn't go by brand aka powerline etc, it's more specifically about the model you're looking at.
    For example D-Link and TP-Link are both manufacturers who I've personally used in the past and had no issues, but they have produced bad products in the past.

    I would fish around for some recommendations, but I'm going to bed very soon as it's ~3:20am here.
  5. thanks good night ill go to bestbuy tomorrow and see what they have and all i can always test and return or keep if its working for me :p
  6. You'd really have to invest in an expensive router in order to get that speed. Either that or an Ethernet cable. For instance, this is what I get with a 100$ router.
    I could get more by upgrading my router, but I don't even game anymore.

    tl;dr: expensive router or Ethernet cable.
  7. If it's just for your computer, buy an external antenna.
  8. i fought a powerline n got even worse speed for some reason lol i bought a AC enabled 5ghz wifi adapter which helped but expensive
  9. Nah Powerline is very decent solution these days :)
    I Always sell them to my clients when they have this problem.

    A decent powerline is about 60€ and a decent router about 40€.
  10. I bought one from best buy for 89.99$ cad, tried it got even shitty speed then my normal wifi xD so I returned it
  11. I was having a similar problem, but it turns out it was this ACK timing setting that was misconfigured. I found out a lot of cool tricks in the process of fixing that. What you want to look into is making sure your modem is compliant with the latest DOCSIS standard so you are getting the highest speed possible. (Most likely it is so) You also want to set the QoS metrics so that it scales the transfer window to the right bit measurement. If your router or laptop comes with usb 3.0 ports then disable that feature as it will create interference.

    I highly recommend trying out one of those alternative router firmwares like DD-WRT or Tomato. They will allow you to adjust the antenna settings and try different routing algorithms like Vegas, Cubic, Highspeed. I can now pick up my wireless network all the way at my friend's house down the street.

    System tweaking guide:

    ^ The settings there for lowering response time is like godmode for some online games.

    Some extra tools:

  12. im not too good with these computer things so let me try to understand,
    So the ISP im with is Named rogers which is all over Canada, the modem they provided me supposedly its their best has all the 5ghz ac enabled feature I been having a lot of issue with their modem cause the stupid wifi keeps turning off while the Ethernet internet would still work. so you said get it to
    1)docsis standard, which I believe might already be since I just got their newest crap
    2) turn of the usb port settting on the modem
    3) set the qos metrics to allow it to scale the transfer window to the right bit measurement (Which I don't understand)

    and u said about alternative router firmwares explain that too if you can thanks:)
  13. Those combo devices are shit and its an extra monthly fee slapped onto your bill. You need a modem that can handle channel binding to reach the kinds of speeds you mentioned. The 5ghz ac feature is only for like a couple meters away and it can get some interference from legacy bluetooth devices that don't negotiate channel rights.

    The biggest problem with wifi is: green energy efficiency power saving BULLSHIT!

    Those penny pinching hacks will trash your signal.
  14. my modem is free with my plan :D

    that shit look like a beast i bought a similar one but that one was ac1900 lol but ya urs a beast
  15. If you don't want to run an ethernet cable all the way to your PC you could run one half way to an open area and install a Power over Ethernet access point, specifically an 802.11 ac. Access points can be mounted on walls/roofs so you would have to run the cable accordingly and hide it. The only concern would be the price, 802.11 ac PoE access points can cost a shit load.
  16. Looking like that and with a name like "Nighthawk" I would think that is one of those new drone aircraft and expect it to take off out a window. Is there an ulterior militarized purpose

  17. There seems to be quite a bit of misinformation in this thread.

    The best way to get stability and speed in any structure is a combination of cabling throughout your house and separate access points connected via Ethernet. No cutting edge technology required, just plain stable Ethernet cable connecting the access points. For your house the best setup would be to probably have a WLAN setup on the top of the bottom floor and the bottom of the top floor, you could direct the signals so as to have a stronger signal on both floors.

    Second best is MoCA, it can extend the internet signal via existing coax TV cable throughout the house. (See this page) (Not to be confused with powerline networking). This can put the furthest connection up to 70 Mbps at best.

    Third best is powerline, though this can only really provide 40 Mbps, with newer types providing a less stable 80Mbps.
    A network like this could look like this:

    There are already solutions that do this for you easily.

    New wireless routers to improve your signal across your home almost NEVER work out, here's why.
    1. Higher throughput does not equal wider coverage. "Throughput gain requires three-stream capable clients and is seen only under strong (same-room) signal conditions and degrades very quickly as signal levels fall."
    2. Higher power does not mean you will get a better signal. As communication with a router requires a two way connection, it is fundamentally flawed to think that increasing the power on one end will solve anything for the second device.
    Many people will tell you otherwise, but unless you own a router older than a WRT54G (2002...) you won't see noticeable improvements across distance at all. This is a mistake many uninformed home network owners will make, and the reason networking companies can make a noticeable profit.

    Wireless extenders won't work either, because there at minimum a 50% decrease in throughput when you extend the signal.
