wifi download speed problem .....

floete 547 75 August 25, 2015 at 05:39 AM
on my main laptop, which is located about four feet from my wireless router/modem, download speeds are around 2.4 Mbps, which is miserable. if i hook up directly w/ ethernet cable, i'm good to go at 26 Mbps. Guess I'll leave it hooked up but I still would like to figure out what the issue is w/ my wifi card, if that's what it is. i have updated the driver and that didn't change anything.

also: i have an older laptop about 30 - 40 feet from the modem and it's getting 20 Mbps, according to speedtest, so i don't think the modem is the problem.

thoughts, anyone? thanks!

Details please..... What is the make, model of laptop and wireless card? How about your modem and router combination?

Try this app on your phone:

Go room to room and test the signal.

Maybe too many of your neighbors are using the same 2.4Ghz channel and you can just change your channel.

Have you tested both laptops, side by side?

gots to be the laptop. i downloaded an app called wifi analyzer. signal strength right at my pc is -40. next to my other laptop in another room, it drops to -80. and in another room where i have a fire stick, it's -70.

laptop is a three year old plain jane dell inspiron. wifi card is generic, i think: dell 1703 802.11 b/g/n.

don't think it could be the router or modem, since every other location works tip top.

suggestions? and, no, sadly i don't read chinese.

2.4Mbps sounds suspiciously similar to the real-world performance of 802.11b. Could just be a red herring though. Does your router have a management interface where you can get information on each client's connectivity?

I'd also recommend playing with different bands / network settings and see if anything improves (short version: you should be running your network on either band 1, band 6, or band 11, whichever has least interference). If you can force 802.11N or G only mode on your router, give that a shot too.

If none of that pans out, I guess you could get yourself a cheap USB wifi adapter. There are a ton of them on Amazon with instructions in English.

it's a laptop, why don't you move it to more places to test.
move to the "fast" old laptop location, if fast, it's interference. if slow, laptop itself.

i nearly tossed out mah old wifi router... i think it autoupdated one time and somehow, it forgot the proper channel it should broadcast on.

internet speed would slow down to like dial up... (signal on lappy was -80 dBm ... next to wifi router), when plugged... it runs fine.

I manually set broadcast channels on router and see if there are improvements (use free widgets to find out signal strength on ur lappy), then set it back to auto. Its been fine ever since. (-50 dBm in my room)

* important: dun chew wifi antennas... uh... dun ask how i kow.

You can check whether the virus infringe the speed. I used to meet the issue before.

I was having a similar issue with my Intel 7260AC card. I had 0 issues on my previous USB 3.0 wireless card. Turns out for some intel (and possibly other) wifi cards you must have WMM enabled on the router or else speeds are capped at 54mb/s.

Most apple hardware also requires WMM these days.
