Slow laptop wireless speeds

J03 6,666 601 July 19, 2016 at 06:23 PM
Hey all, I've got an issue I've been trying to resolve for quite some time now and I've just about exhausted all the standard attempts to solve it.

So my laptop has very slow wireless speeds. It's the only device in the house with this problem. It has an intel wireless n 7260 adapter and it's a Lenovo Yoga running Windows 10. My router is an ASUS AC router. I just ran a speed test on this laptop from across the room and I got 17.78 down, 4.20 up. I ran speed test on my phone at the exact same time right next to my laptop and pulled 51.7 down and 3.8 up. I then moved my laptop and phone directly next to my wireless router and ran the tests again, this time pulling 47/5 on the laptop and 92/6 on my phone. I have a 100Mbps connection so my phone seems to be pulling it's full potential while my laptop never does. I ran these tests on unmolested Internet Explorer (or Edge now?) so I know it's not an add-on messing with it.

What I have done so far:
-30 sec restart on both my modem and router
-updated wireless drivers to the latest via windows settings
-deleted wireless driver altogether and installed an even newer version of the driver I downloaded direct from Lenovo

Anyone have any ideas as to what could be causing this?

Thanks,

J03

Your phone may be wireless AC and\or may be using the 5 GHz band while your laptop uses the 2.4 GHz n band.

One thing at a time, leave ur phone outta this for now. So, u already know lappy speeds while on wifi.

1. physically plug ur laptop directly into the back of ur modem and run speedtest

2. physically plug ur laptop directly into the back of ur router and run speedtest

if those are similar to wifi #s, give ur ISP a call and tell them u are not getting rated speed.

if u are getting rated speeds when physically connected, just not wifi... then bottleneck might be that wifi thing... could be channels too similar to existing networks... pick a channel further from neighboring channels. Is ur lappy overheating? etc...

My older N tablets don't seem to have the same issue as the laptop either.

Ah yes, forgot to mention that I do not have an Ethernet port on my laptop. It's wireless access only. I'll try running a speed test on my directly connected TV or Xbox if it's available and report back. However I don't believe the router or modem are the issues since my other wireless devices speedtest at the advertised 100.

does it come with a tool or in it's properties has options to choose performance or power saving

or the laptop itself's power option

Are those N tablets 2.4ghz only or 5ghz as well. There's several models of the 7260 including a single band N, dual band N, and dual band AC. With the saturation of the 2.4ghz band 5ghz is generally going to give much better performance, even if they're both 802.11N devices.

You could always buy a USB to ethernet adapter(and if you really don't want it, return it when you're done lol).

Provide the detailed properties (brand and model number) of your wireless adapter. I'm betting it's an inexpensive 1+1 module, whereas 2+2 modules are available that provide higher performance.

what link speed when close to router
not sure if that router can see link speed too, compare the speed, maybe not working at 40Mhz

try change router setting to 20mhz N only, see if other devices still much faster

disable 2.4 then 5ghz on router, if don't want to use different SSID, see if both band same speed

Great answers here. Quite a few routers now send the signals as the same signal name and expect the devices to sort it out, you'll definitely get faster speeds on 5ghz though you won't get the distance.

A usb to nic could be an option as well as a usb to wifi.

Finally a 30 second restart of your modem and router won't do much. If you want to get a refreshed signal from your isp you should wait 3-5 minutes (as well as make sure any connected battery is removed).

Hey thanks for the suggestions guys but after trying a lot of different options in here I finally decided to just clean install Win 10 to this thing and googled to see how others with this particular laptop did it without issues. Well I just so happen upon a thread where Yoga 2 owners were trying to clean install to fix their wifi issues and one of them mentioned 'the bluetooth mouse still slows wifi to a crawl.' Well sure enough, as soon as I turn my bluetooth mouse off the laptop wifi speeds are perfectly fine. Then with it on they drop to roughly 1/3 the speed. It's nuts but somehow there is interference between the two. I'm glad to have my speeds back and I can buy a wired mouse but I'm bummed I didn't discover this sooner to get it replaced under warranty.

Also, you can get a wireless mouse that isn't bluetooth (instead of buying a wired one) like this Logitech for $20 [staples.com] that won't interfere with wifi signals

Back in the 802.11b days...I could bump my lap partner off the School WiFi just by turning on the BT radio in my laptop.
