WIFI only connects after running troubleshooter....

[Ongkanon]

The router has three connection options:

b & g

upto 65mbps

upto 150mbps

It is set to upto 150mbps

Ok, I haven't seen it listed quite like that but should be n only.

I can't say why that connection software can't be uninstalled but that may be part of the problem.

The fact that you can connect with security disabled might indicate that you should update the firmware on the router.

 

[Ongkanon]

I have checked and the upto 150mbps is for 'n'

I will concentrate on the uninstall/error message issue and try to resolve that in the hope it will allow me to move on.

Again I have to go to work and will be back on the cast in the A.M.

I have now uninstalled the afore mentioned software and reinstalled the Broadcom driver.

The router has the latest firmware version installed.

Still having same issue.

I am starting to think this will never be resolved!!!

 

[boohbah]

what number do you have for the atheros driver.
the latest one is available here
im using it successfully on a lenovo G555

Atheros & Zidas drivers

 

[Ongkanon]

Excuse my ignorance but will that driver work with my adapter - Broadcom 802.11n ?

 

[Ongkanon]

Ran setup.exe from the CD folder and get an error message "The installer can not run on this platform. Please select package for your operating system"

OS is Windows 7. The other setup.exe option available in the main file doesn't run on my system.

Been researching again this afternoon.

Could this have anything to do with the 8 Wan Miniport entries in device manager.

Some suggest that these could be the cause of a number of WIFI related issues.

 

[Ongkanon]

These are the devices listed under Network Adapters

 

[chev65]

Those drivers won't cause any problems.

From what you are saying the problem tends to point to the router, the fact that when you turn off the security then you can connect without problems tends to implicate the router, maybe some type of compatibility problem between your router and the drivers.

 

[Ongkanon]

I have tried turning of security again today and it didn;t make any real difference. And we have another two computers connected to the router and working fine. Whilst I don't mind buying another router, what if I do and get exactly the same issues.

I will carry on trying to find a solution for a while longer.

 

[Ongkanon]

Another suggestion I have seen is to delete 3 system files associated with the adapter and then re install the drivers. Anyone know how effective this would be?

Excuse my ignorance but will that driver work with my adapter - Broadcom 802.11n ?

sorry, my mistake, after asking the number i went on to inform you of the latest update for my drivers.


assuming they were the same. brain fart i think!
hope you get it resolved soon.

before you run the trouble shooter next time try and disable the network connection then enable it and see if that makes any difference.
open network and sharing center /change adapter settings.
then on your network connection right click it and disable, then right click and enable.
if this works it may be easier that the trouble shooter each time. until you get it resolved.

who is your isp?, out of interest.

also if you open device manager and expend the network adapters tree, right click on your wifi and select properties /driver tab ,it will have the information as to the number and driver version.
if you post the driver version then its possible we can see if there is a newer version somewhere

 

[Ongkanon]

Sorry for delay in response.

My ISP is KCOM (Karoo).

Herewith driver details from device manager:

 

[boohbah]

have you downloaded the driver from lenovo at some point?
oddly it says its for windows 8, though i cant see the harm in trying, its only a rollback if not!

Drivers and software - IdeaPad Z585 Notebook

 

[Ongkanon]

I have tried to install the Lenovo driver for this machine before and it gives me an error message saying the system is not supported and it will not let me install.

There is a drivers folder on the computer with a Wi-Fi driver folder and thats the one that installs.

So the assumption that it is a driver problem appears to be correct but how do I get the system to allow me to install the correct driver?

I bought the machine as nearly new and it came with WIndows 7 pre installed along with the WIndows DVD and product key.

This has be baffled.

 

[boohbah]

did you create a recovery disc when you first got the computer? , that would have the drivers on it.

did you try to disable the network connection and re enable it.
i think chev is correct as it connects eventually its probably not a drivers problem, im probably sidetracking the real issue.

 

[Ongkanon]

I didn't create a rescue disk thinking the original DVD could be used if I need it.

I have tried to disable and re enable the network connection too many times!

All the the info I get from the troubleshooting reports suggest a driver problem.

I would like to try and get the correct driver installed but I have no idea how to sort this one out!

 

[Ongkanon]

OK installed the correct driver after changing some compatibility settings (the setup file was configured for XP).

After checking the driver details in device manager, the numbers have not changed.

 

[boohbah]

i dont suppose you have an nvidea ethernet driver?( NVIDIA nForce Networking Controller )
