Elitebook 840 G1 Wireless connection issues

[roymeboy]

The antenna for the wifi runs around the screen so depending on interference and what not, having the lid open could well have an effect on performance.
We have a lot of these machines in work, whilst I don't like them for various other reasons, I haven't heard about or noticed a general problem with slow wifi performance or speed dropping over time, but this could easily be overlooked in our place. I'm gonna check this one out when I get back in, got a week off though so update will be a while. Thanks for the heads up, the amount of problems I've had with these, I wanna get all the issues resolved cause its downright embarrassing having no solution to these problems which all appear to be driver/bios related at heart. Just waiting for the fixes, then the fixes of the fixes, then the fixes ... you get the point

Hi,

I am having issues with my wifi connection at home using  my new Elitebook 840 G1 running win 7.

So I connect with this laptop to my wifi device and I can access the internet as usual. But after some time (varies from 2 minutes to 1 hour) the wifi indicator in taskbar on the bottom shows no internet access and I loose the intenet connection. I have to restart my router and I get to connect but same story after a little while.  I have to place my router next to my bed and have to restart it all the time and it is getting really on my nerves. 

Some more background info: The laptop can connect to my office WLAN network without any issue for whole day. I have tested it on two different networks. I have reinstalled the wireless drivers but to no use.  On the other hand Router is and was working fine with my old hp notebook 4530s also it shows no issues when i am connected via android device.

It is just that when I connect Elitebook 840 G1 to my home network, the problem mentioned above starts happening i.e no internet access. Can someone tell me whats can be wrong here? what settings might cause this issue.

Thanks

Umair

I am also experiencing similar behaviours to several of these posts.

I have updated all drivers and BIOS to be current - nothing is outdated.

I connect to my wireless network without issue and have a good / strong connection - after a while (1 to 2 hours) the 840 G1 laptop loses connectivity to the internet but can still see my wireless network.  

My other devices, iPad, iPhone, Gateway desktop, all maintain wireless and internet connectivity.

After rebooting the laptop we restart the clock to the next disconnect and reboot.

This is very frustrating and as so many have posted similar issues, HP must be aware and have a solution.

I am having similar issues with WiFi disconnection after a while (10 mins to an hour).

The WiFi simply disconnects and will not reconnect. The only solution is a cold boot which resumes functionality for a while.

This is happening on all FOUR recently aquired HP Elitebook 840 laptops.

I have tried changing the power settings, updating BIOS and drivers (latest drivers from both HP and Intel have the problem) and have observed the problem occuring first-hand (the laptops are teacher's laptops at a school where I work as ICT support).

Thinking that the issue was that the laptops had been rebuilt with the schools default OS image (Windows 7 Enterprise x64), and that that was at fault, I then rebuilt one on Windows 8.1 Enterprise x64 and it STILL has the disconnection issue!

We are using Ruckus AP's and all other devices (hundreds) do not have any issues.

I bought the same laptop several days ago (Windows 7 x64, latest BIOS). Similar symptoms occurred today – after 10-40 minutes the Wi-Fi internet connection is lost. The network is connected, but there is no ping to gateway. Diagnose of the connection temporarily fixes the problem. I did some modification and it’s stable afterwards. The steps you can try are:

1. Uninstall the Broadcom Wi-Fi driver from Device manager with the option to delete the driver. If the Windows reinstalls it automatically – repeat the same until it becomes an unrecognized device.
2. Install version 5.100.82.147 of the driver from the HP website.
3. Check Windows update. You will see Broadcom driver pending update. Hide it to prevent from updating.

My Wi-Fi is stable since then (about 8 hours). I will write if the problem still exists.

Update (18.02.2015): Connection is still without drops with driver v.5.100.82.147. Versions 6.30.223.181  and 6.30.223.228 are highly unstable.

The speed is lower than other laptops in the same conditions - 25-45 mb/s download (HP 840) vs 40-60 mb/s download for other laptops (2 Acers). The upload speed is better - about 60 mb/s, which makes me think it is a driver issue, not hardware. I'll wait for newer driver version.

Update(22.02.2015): Using non-HP provided drivers fixes the speed problems. The version is 5.100.235.19 (you can google it for the link). I installed them from the device manager with the update driver option, but had to delete the previous drivers first, because the date of v5.100.235.19 is older then the HP provided drivers and Windows won't install them. I hope this will fix you problems too.

Thanks for your post ~ Is your connection still stable?

Has anyone else tried this fix and experienced the same success?
