Atheros Ar5b125 Driver Windows 7 (32 Bit)

[Stefanie Mordaunt]

Youcould download the latest NIC driver from ATHEROS Wireless drivers for Windows. Search for the AR5B125 line and click on the green V sign for your version of Windows 7 (32-bit or 64-bit). Reboot after installation.

If installing the driver does not fix the problem, go into Windows Update and ensure that your computer is fully patched for both important and optional updates. Call Windows Update repeatedly as long as it can find anything to install.

It the problem still persists, it is worthwhile checking if the cause is not hardware. Find an external USB WiFi NIC and try it out. If this fixes the problem, then the built-in NIC is faulty, and the question then arises whether the computer is still under warranty.

This might be a problem with the wifi channel you are using. If you have a router that is commonly used (like a fritz box or something like that), then its default channel might be swarmed with connections and interferences. Some routers have a graphical display to show the load of interferences on its channel. I suggest you to set the wifi to a more uncommon channel (like 12 or so) and look if the error persists.

Wi-fi is very finicky when it comes to line of sight. You need to describe your geographical environment in terms of location from access point. For example, if you are close to the access point or if there are walls in the way. Wireless (2.4GHz) does not work that well through walls because it's a high frequency (in contrast to cellular technology which is amplified on a low frequency).

If still problem persist , now try to connect your laptop using ethernet LAN cable through modem . Your ADSL modem working fine as you told , so you need to check weather your both network adapters are working fine or not ,to figure out the problem .

If you face the same problem in LAN connection again ,then problem may be with your windows drivers and recently installed drivers or viruses etc. The fresh re-install of your Operating system will sure help to resolve this issue

Try checking your antenna wires inside your laptop that they are FULLY intact. Any loose or overly bent wires will randomly stop your wireless from working, especially during whilst the laptop is moving. Either way, no harm in soldering them on properly if they look a bit delicate.

your ADSL router could also be the issue here as it could be broadcasting in mixed mode using both frequency bands (ie. 2.4GHz - 5GHz). Broadcasting in both bands can cause conflicts and issues with connectivity. I would log in to your router and check the wireless frequency broadcast. I would also investigate the power settings on your router to verify the antenna strength is sufficient enough for the area you are using the machine in. I would also test out the issue while using a static IP/Subnet/Gateway/DNS/ to verify that your machine or DHCP isn't having any issues reissuing IP config settings.

If your problems still persist i would use a third party diagnostic tool to interrogate your system for faulty hardware or as a previous suggestion try out a wireless usb adapter to see if that will isolate the problem to a faulty NIC card.

I have also had a similar problem with intermittent Wi-Fi connectivity. The option that finally worked for me was going to Device Manager -> Network adapters -> (Your Wi-Fi device) and deleting the device along with its drivers. Then, I rebooted my computer, and let Windows detect my Wi-Fi device and reinstall the driver. After that, my Wi-Fi connection stopped dropping. This may be not the solution for everyone, but it is an option that worked for me. Download backup drivers from Internet before deleting device from Device Manager in case Windows does not have the correct driver pre-installed.

As we could not solve this problem, we finally installed a USB WLAN adapter, and disabled the built-in adapater in the Windows device manager. This has solved the problems. So it looks like it was a problem with the built-in adapter.

I had this problem with the Atheros/AR5B125 in my ASUS X555LA-HI31103J and had updated the drivers. I have configured the PC for dual boot Windows 10 and Ubuntu and it occurred IN BOTH OSes. The problem was reduced by configuring my WAN at home as suggested here, but, when I travel or go to coffee shops I have little control over that. I finally gave up and removed the OEM network adapter and replaced it with an "Intel Network 7260.HMWG.R Revised WiFi Wireless-AC 7260 H/T Dual Band 2x2 AC+Bluetooth HMC" on Amazon and have had no drops since. What a relief.

I will say the change was harder on this PC than most, it is buried under the motherboard which required removing EVERYTHING down to the plastic shell, almost lost my nerve, but finished the job and am ever so glad I am rid of this problem.
