I have cable Internet that averages about 35 MB/sec down and 7MB/sec up, but been having intermittent Wi-Fi problems for several months now. I’ve changed my router a couple times to no avail. I’m currently use a TP-Link Archer C9 (AC1900 Wireless Dual Band Gigabit Router).
Seemingly randomly, the connection over the Wi-Fi seems to get incredibly slow. Down to less than .25 MB/sec down and .05 MB/sec up. (I use speedtest.net to measure the speed.) Following some advice on here I’ve attempted changing the Wi-Fi channel and channel width and this seems to fix the problem for a short time before reverting back to being slow.
This isn’t just an Internet connection that’s slowing down. Accessing the router admin panel or transferring files over Wi-Fi is incredibly slow, as well. I don’t live in a very congested area, with only a couple other networks showing up, even hidden networks. I do have many devices on my network, 4 phones, 2 tablets, 2 laptops, an Xbox 360, an Xbox One and 1 desktop (plus 1 wired desktop), but only a few of them are ever being used at once.
- All the laptops and desktops are running Windows 10.
- The phones are all Android including a Moto E and an HTC Desire.
- The tablets are Kindle Fire HDs.
- The wireless desktop is a Dell XPS Special Edition with an Intel Dual Band Wireless-AC 7260 card.
I’m at a loss of what to try next. Any help would be appreciated.
You need to edit your question to add more specifics. Such as what is the make and model of the Wi-Fi adapters you are using and maybe what the OS and make/models of the systems you are using are. – JakeGould – 2015-11-01T18:27:42.230
Added some details. – NicholasJohn16 – 2015-11-01T18:37:14.697
Can you explicilty state that the wired desktop internet connection does not slow down when the wireless connections do? – Andrew Morton – 2015-11-01T18:46:31.703
It does not. It's always fast and never had an issue with it. – NicholasJohn16 – 2015-11-01T19:24:24.637
Do you have a proper placement for the Wi-Fi antenna, and is it positioned correctly for the placement? – Ron Maupin – 2015-11-01T19:32:22.000
My house isn't that large for distance to really be an issue. The wifi router is just down the hall from the wireless desktop. All the devices receive a strong wifi signal. – NicholasJohn16 – 2015-11-01T19:49:03.410
Does the speed revert to normal at any time? For example after a washing machine stops running - could it be faulty wiring somewhere causing a lot of electrical interference (you could wander around with a portable AM radio to find out)? – Andrew Morton – 2015-11-01T20:33:35.930
@NicholasJohn16 Can you clarify what units you mean when you say "MB"? Is that MebiBytes (1,048,576's of 8-bit bytes) or megabits (1,000,000's of 1-bit bits) or something else? – Spiff – 2015-11-02T19:23:27.470
It's Megabytes. The wifi does speed up at times, but there's no regularity to it. Is there anyway to track the bandwidth usage of all devices on a network? – NicholasJohn16 – 2015-11-02T23:16:14.777
Have you tried disabling the 2.4Ghz and testing completely on 5Ghz? – Linef4ult – 2015-11-04T10:56:29.943
