Wireless running slow, full strength, other devices off

Hey guys, recently my laptop has been running a bit slow despite being on full signal strength, it isnt even that far from the router, ive tried resetting the router but i dont think its the cause because my pc connected via ethernet is still running at max speed it normally reaches. Even when the pc is turned off the laptop is still slow, im wondering if anyone has any ideas.

There are some router settings that will allow your 802.11n devices to run at full wireless N speeds but you need to use the 802.11n Only setting in your routers wireless set up page. The only draw back is that your legacy devices running wireless G or below won't be able to connect any more.

This setting will allow you to connect at full 802.11n speeds, the mixed settings would have you maxed out at 54Mbps where full speed can be up to 450Mbps for wireless N.

Thats gonna be a problem if some devices connected dont support N speeds... guess i better check compatibility before i change that setting

Hi there,

In addition, you may also change the wireless mode setting from your Wi-Fi adapter if available.

Is it in general it's slow? Perhaps when you are browsing or gaming, etc....?

Honestly that setting is what you would use to improve wireless speeds but probably has nothing to do with your problem. The facts are there are a million reasons why your wireless appears to be slowing down, it can be anything from A/V software to a virus. These types of problems are extremely difficult to track down.

Your best bet is to start up in safe mode with networking to see if the problem persists. If the problem goes away in safe mode you can be sure there is a program or software or a virus on your machine that is causing the problem. Fixing it can be quite an adventure but it would at least narrow it down.

It's option 3 number 5 in the link below.

In addition to chev65's post, possibly try booting your machine into Safe mode with Networking to see if there is a third party application that may be slowing your speed down. Also possibly try to temporarily disable your A/V and test?

To boot your machine follow this (Option one) - Safe Mode Please replace all references of 'Safe mode' with 'Safe Mode With Networking

The settings are fine but you need to start up in safe mode with Networking in order to narrow down the problem.

If the slow wireless problem doesn't occur in safe mode then you can be sure the problem is caused from an installed program or software.
