Slow internet on 1 laptop but not the others.

Basically. I have my Laptop, that can't get speeds to 50mbps, and always gets about 10-15mbps on 50mbps internet.

I am wireless, and literally on the other side of the wall where the router is, plugging it in warrants 54 download, all other devices in my house on the 2.4 and 5.0 internet receive max speeds even my older Vaio in my room.

I have already gone and reinstalled my wireless drivers, tried a speedtest in safemode with no improvement, I can't see how it would be the router considering everyone else is fine.

I really don't want to believe it is the wireless adapter itself, considering Lenovo has a diagnostic hardware software that I had run a few times now saying its fine. The laptop has been given great care, and well. Wireless cards don't just up and die, I wouldn't think.


I don't have anything specific, and couldn't really find anything specific but the wireless card is a Lenovo Thinkpad 1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter (Made by Realtek) Drivers are dated to 2014
 

I am hoping we can find out what is wrong, Maybe my Router has a grudge against my laptop or something, I have no real idea. But I am a gamer and ping flaring up, slow downloads for steam, and streaming is just. Sigh.. Sometimes it reaches 30mbps but wireless it hasn't gone to 50 ever.

We already called TWC, and I have gone through the router page to find anything out of the ordinary (Following ASUS support and manual)


Please have a magical cure.


Edit- It is midnight and I am the only one online. I turned on the Asus QoS, and I get 43mbps, I am now lead to believe it might be my router, but question why everyone else reaches max speed still when everyones using the internet except me.

Also I know this is about computers so I don't know if router stuff counts or not :/

Wireless cards can just up and die, they can also slowly die and just get worse and worse.

But in this case it could be a number of different things. Some routers don't work the best with all wireless adapters out there, a lot of times there is firmware updates for routers to help improve the performance with some adapters.

It could be a number of things, the router, the wireless adapter, crappy drivers, the material in your wall between the adapter and the router and so on.

Right now there is 2 common factors. The router and the adapter itself.

You said the other devices work fine with the router, that is most likely because those are different model adapters and so they work differently. We know it isnt windows because plugging in a network cord gives you the full speed.

It could also just be that your router just needs a firmware update to better support more models :-)

I have the newest firmware for the router.

I have tested my Vaio laptop in my room, and tested the wireless while next to the router, I receive the terrible speeds all the same.

I actually have a Amazon Kindle Fire HD 6, only 4 months old, that seems to get slow speeds too.

I really hope it isn't the wireless card dieing, I do have much older computers (a toshiba from 2003) with working wireless, and the Vaio I have you can hear stressing itself to continue running, I just find it way to coincidental for the newer more taken care of laptop to die.

It might potentially be the drivers, but I can't figure out what realtek model or whatever information I need for what the wireless card is. Since OEM drivers from Lenovo haven't been the grandest or up to date things I have had joy of using.

Anyway ways to narrow down the cause? If I take my laptop apart and check the wireless card will it have any noticeable difference then it did several months ago when it worked?

Otherwise we have a 50 foot ethernet cord I could convince them to let me run to my bedroom.

Shane:
Nice thing is, in the laptops the wireless is just a small chip that can be taken out, and even replaced with a different one, from another laptop.

Drivers do play a big role, so does the router, and of course the adapter, this is why it is such a pain in the butt lol

For my devices at home, I was getting bad speeds on some of my devices and I tweaked my wireless settings and got the speed up.

First the wireless security has to be WPA2 AES in order to get the higher speeds.

Now I use the 3rd party firmware DD-WRT because I simply get better performance than the factory netgear firmware in my router. So here are my wireless settings, you wont have all these options in your router, but for the ones you do have you can try tweaking closer to mine and see if it helps. Of course after any changes to the wireless are done in the router make sure to reboot the router after.

Even though all other devices (except the Kindle) work fine, simply rebooting the router can do it.

You can check which wireless adapter the Lenovo is using by pressing the Window key or clicking on the Start orb and type devmgmt.msc and press enter - click on View/Show hidden devices then expand Network adapters.

The quickest way to renew a wireless driver is to wire up to the router, right click on the wireless adapter and select Uninstall, but do not check the box to include software - and then reboot where Windows will reinstate it.

While I don't have an explanation for the Kindle, check to see if the laptop's speed is just as slow when booted up into Safe Mode with Networking.

With the speed being normal when wired, it probably isn't anything running in the background, but in normal mode go Start - type resmon - press enter and under the Network tab you can check which processes are using network activity as well as the total network activity by expanding the window below the top one.

To check the signal strength between the laptop and the router, open a command prompt and enter netsh wlan show networks mode=bssid

This will show the signal strength against the router's SSID.

With the laptop next to the router, it should be at least 98%.
