slow wifi

I've Been Around

so i believe its been the past 4-5 months that i have been having a problem with my wifi. there are 3 people in my house that use the wifi at the same time and in december january and february there was really no problem at all with speed but i started noticing thing like being disconected from the interne while using wifi with my devices which are laptops and phones. now after being on the phone for an hour with a lady that had no idea what she was talking about kept getting me to check the internet speed which i couldnt because i couldnt be on the internet any longer then 3 mintes before my router would restart she then told me to reset it myself using the usb that the tech had left. after reseting my router the problem was fixed for about 2 weeks and all of our devices were back to disconecting because the router would reboot this problem has since then dissapeared with no explanation but we now have a new problem and that is extremely slow internet while using the wifi when i play online game mainly nhl14 and league of legend i experience extreme amounts of lag but when im connecte through an ethernet cable the lag goes away now i could obviouslyjust connect my laptop and ps3 to my router everytime i want to play but that just takes out of the convienence of being able to play wherever i want in my house i just want to know if there is any way to fix my wifi speed so i dont have to directly hook up to my touter everytime i want to do something.

Re: slow wifi

I am having a plan with 30 mb download and 5 mb upload speed. Internet speed with direct connection on one of my laptop is normal (around 30 mbs). But speed on WIFI is extremely slow even next to the modem (Tested on several devices, all got less than 1mbs speed). Customer service from Rogers said the problem is due to wifi signal interference. Any help on the issue? Would a wifi extender be helpful?

Re: slow wifi

A wifi extender might help, but, my advice is to buy a good router with external antenna and gigabit WAN and LAN ports.  That would probably be a better solution than a wifi extender. 

 

Here is some food for thought. Load inSSIDer on your laptop, which is a wifi monitoring application. When loaded on a dual band laptop, inSSIDer will monitor both 2.4 and 5 Ghz networks that can be detected by your laptop. Have a look to see what you're competing with in both bands. In a suburban area, the 2.4 Ghz band is usually pretty crowded and tough to work in, so, I'm not surprised that you're having problems. Usually the 5 Ghz band is less crowded and easier to find a clear channel. After you have a look at the display, you might be able to determine if there is any 2.4 Ghz channel that is clear enough that it might work with the present modem. Never know unless you have a look, using something such as inSSIDer. The program link below is for the last freebie version. A new version is out now that will handle 802.11ac networks in the 5 Ghz band, and which will work on a 802.11n laptop. The new version will read the broadcast management frames and display the 802.11ac networks that are running in the 5 Ghz band. Its worth the $20 U.S. to buy, so that you can see all of the networks that are nearby.

What you want to see on the graphical display is that your network is the highest network shown, which indicates that it has the highest received power of all the received networks. Generally you want somewhere in the neighborhood of 40 to 45 dBmW separation between your network and any other network that is on the same or overlapping channel. So, while your network should be the tallest on the display, everything else should be well below yours. When that power level separation decreases, you end up with interference and possibly with problems maintaining a wifi network. Your only option is to change to a channel with less overlap from the competition. By looking at that display you might conclude that the 2.4 Ghz band is hopeless and that its time to move up to the 5 Ghz band, if you can. If you have devices already running in the 5 Ghz band, look at channels 149 and higher. If you can switch to any of those channels, do so, as the output power for those channels is higher, resulting in better signal levels, signal to noise ratios and data rates.

 

Fwiw, the Hitron modem does not support beamforming, which is part of the 802.11ac spec. That allows the modem/router to aim a focused signal towards the laptop/device, etc, etc. The result is better signal levels, signal to noise ratios and data rates at the device. The RT-AC68U as an example, now replaced by the RT-AC68P supports implicit and explicit beamforming, meaning that the router can determine on its own where the device is and focus a directed wavefront in the device's direction (implicit), or, in conjunction with the device, direct a focused wavefront toward the device (explicit). Here's a link that provides some explanation:

The other part of this is the actual device itself, or, more importantly, the wifi card. We've run into far too many examples of new, really nice laptops that are well thought out except for the cheap wifi card that was included. End result, much disappointment at the wifi performance. The way to determine that, for a laptop, is to drill down into the Device Manager, grab the wifi adapter model name and number from the Device Manager display and run a search for the manufacturers data. A 1x1, meaning a single antenna for transmit and receive will limit your data rates. A 2x2 meaning 2 antenna is normal but not guaranteed. This or better yet, 3x3 will provide better data rates. If you run a search you will also come across posts regarding difficulties that other users might be running into with that card, so it may give you a better idea of what you can do to improve the wifi performance.

No... in fact, the way wifi extenders work, they'll likely make things worse. 

 

 

My view:

1) Download something like inSSIDer to see how many other wifi networks are around.

2) To some extent, you can improve things with a higher-powered router/access point (e.g. the RT-AC68U) than the Rogers gateways. 

3) One other option is to move as much of your traffic as possible to the less congested 5GHz band... assuming, of course, that your client devices support 5GHz. (If your client devices have lousy wifi, that doesn't help)

High speed internet problem

 

Hi I'm having a problem with my internet i experience slow downs randomly range randomly gets smaller I've contacted Rogers and all they said was its just wifi

Re: slow wifi

Can you log into your modem, navigate to the STATUS.... DOCSIS WAN page, copy the downstream and upstream tables and paste them into the thread.  Those are the RG-6 cable signal levels and signal to noise ratios which might be of interest.  The copy and paste process will paste in the text components of the tables, so you don't have to grab a screen image and insert that. 

 

On the wifi side, can you have a read thru my post #47 above and load inSSIDer onto your laptop or pc to have a look at the wifi environment.  If you want to insert an image of that into the thread it would help to see whats on the wifi side of the modem.  If you use Microsoft Paint to paste in the image so that you can save it and insert that into the thread, you can use MS Paint to paint over your MAC address prior to saving and posting. 

 

With both of those on hand, cable and wifi data, we'll have a much better idea of what the problem might be.
