Intel's Wi-Fi adapters connectivity issues continue

The Windows 7/8 disconnection errors appearing with Intel Centrino 6230/6235 adapters are still a problem area, and users are becoming increasingly annoyed with the way Intel are handling the issue.

Sadly, despite even more new driver updates released over the past couple of months, Intel still hasn't got to the bottom of what is causing users to be disconnected from their networks. To make matters worse, users who complain about the fault are now seeing their Intel forum accounts removed.

A number of users have contacted us since our original story went live to tell us that their accounts have been disabled; funnily enough, the posts I had previously made about the issue on their forum have also been removed, and my account deleted too.

What happens for most users, is that when they first buy their new laptops, they will immediately connect to their wireless network; then usually within an hour of use, connection is lost. Reconnecting will sometimes say that the network does not exist, switching the Wi-Fi off and then on again will usually reconnect you, but users can expect the same thing to occur a few hours later.

This is most apparent when either downloading large files at high speed, or when playing online games; disconnections or long sections of lagging will become the norm for many Centrino owners.

Neowin reader Johnny B contacted us to say that he has received the following information from Intel support on the matter recently:

Hello Mr. xxxx,

I’m sorry to hear that you’re continuing to have issues with your Intel wireless networking card.  I’ve spoken to one of our product engineers regarding this issue and was told that there are two upcoming software releases (one within the next couple of weeks and then a follow-on within the next 6 weeks) that should help to resolve a large number of the issues that you are experiencing.

When they are available, you will be able to download these updates from

Again, let me apologize for the trouble that this has caused you.  Our engineers are acutely aware of the impact that these issue have and are diligently working to improve the experience you have with Intel products.

Thank you,

Ron Raymond

For those of you who are still having issues with the latest Intel drivers, you can revert back to Microsoft’s own driver set by selecting your Centrino adapter in Device Manager, and then uninstalling the driver and selecting the option to remove the driver files too; rebooting your PC should then automatically set you up with stable drivers.

These are the drivers you want.

The only other way to get stability, is to go to the advanced section of the Centrino adapter in Device Manager and disable the 802.11n mode, something most of us don’t want to do for speed reasons.

The latest Intel Centrino drivers were released three days ago and the issues still seem to be apparent, but it would be great to hear from any users who have finally got a working network at last.

So once again, we are back where we started, the issue has been ongoing for a year now for thousands of users suffering disconnections, and despite Intel's assurances that their next software release will fix it (as they said about their last three releases) it doesn't look any closer to being resolved.

Same issue with Sony Vaio Duo 11 (which mounts Intel Centrino Advanced-N 6235).
Tried switching several drivers, but still losing connectivity in unpredictable way.
I will try to disable 802.11n mode as a workaround.
This situation is becoming ridiculous.

The 16.5.3 driver package appears to provide the same driver that was already available from Windows Update for 8.1.

I'm having this problem with 6230 for 1.5 years, tried dozens of drivers, no luck. It's pretty obvious this is a hardware problem that Intel doesn't want to correct by replacing adapters so they "promise" to "fix it" "very soon".

Next time I'll ask for a "non-Intel" wifi adapter in the next laptop.

They think they have a fix for Windows 8 systems:

Sporadic but recurring connection dropouts on Intel wireless adapters

Updated September 11, 2013:

The new software is now available for these adapters with Windows 8*:
•Intel® Centrino® Wireless-N 2230
•Intel® Centrino® Ultimate-N 6300,
•Intel® Centrino® Advanced-N 6205,
•Intel® Centrino® Advanced-N 6235.

You can download it from

We are sorry for the upset and inconvenience this has caused. We appreciate your patience and understanding while we have been working to create a solution for the connection issues.

Intel is aware of end-user reports of connection instability (connection drops, applications hang, etc.) with certain wireless adapters using 15.x software with Windows 8 operating system. A software release is planned to support additional wireless adapters. This release is expected by the end of Q4.

hello. i got a lenovo laptop with centrino 6205 card and have been having this problem for months thinking it was my wifi router or maybe windows 8.1 preview.. nonetheless i found this thread and just uninstalled the intel wireless software and no more issues! my issue was the constant high lag spikes while gaming. browsing and downloading is fine, and no disconnect issues.

Just another update - Windows 8.1 RTM makes matters worse as it now installs a non-working driver for 6235's which can't be rolled back to the original Windows 8 working one.

"The only other way to get stability, is to go to the advanced section of the Centrino adapter in Device Manager and disable the 802.11n mode, something most of us don't want to do for speed reasons."

Wait, so the work-around works, but you don't want to use it because it's slower? But isn't a constantly-dropped connection wayyy worse than a slightly slower one?

When you just bought hardware to run in a house with everything else on 802.11n only and its a brand new device - I wouldn't want to use that work around, id rather go with older working drivers.

I have been having this issue forever espeically since upgrading to Windows 8. I need to find a way to get back to that older driver because it has been driving me nuts. I have the Centrino Advanced-N 6300

I have an Intel Centrino Advanced-N 6230 that is also affected by this issue.
On 5Ghz it's OK but on 2.4Ghz it has the disconnect / reconnect / unable to reconnect crap. On 5Ghz the range is pretty abysmal as a trade off.
To be fair to Microsoft's Windows platform as well though, I have similar behaviour under Ubuntu 12.10 x64 (Didn't try 5Ghz).

Quite surprised this has happened personally given that my experience at least with Intel as far as wireless devices and drivers has been pretty good on not only Windows but also Linux and other platforms that support Intel wireless cards. With that being said Intel really need to focus on their software because god knows their own video card drivers leave a lot to be desired.

I have an Intel Centrino 6300. It's the only card that manages to get a WIFI signal on the first floor (very thick walls of an ancient house). On the same floor connection is very stable and never had problems. First floor it's very unstable but I guess it's the poor wifi signal not the card per se... other laptops/mobiles don't even manage to detect the wifi signal, let alone connect.

Windows 8 and WiFi has been a mess. At our school almost nobody with Windows 8 can connect since somehow they managed to reduce the support for WPA2-Enterprise. Windows 7 and all other operating systems and mobile systems are fine, but most Windows 8 devices fail to connect. It's all high-end Cisco gear and nobody really seems to know what the problem is.

It's the same at work - Windows 8 connectivity keeps dropping. We have high-end Cisco routers here, too. Let's hope Cisco/Intel/Microsoft can fix this ASAP, because it's driving us all nuts.

If you disable Wireless N you will no longer see that issue, or at least from my testing. Not really a solution but a workaround.

I have the Intel(R) Centrino(R) Advanced-N 6235 in a HP DV6-7000 and never had any disconnection problem. Router is a Netgear WNDR3700 and I'm using 5G.
The only problem I experience is with my Widi adapter. I usually have to reboot before I can connect to my Belkin Screencast.

Seems like I narrowed it down to driver issues too with my Intel 6300 as well. I posted about it a while back where I was having a hell of a time with wireless stability on 5Ghz to which I changed drivers, routers, wireless card (another 6300) and even the laptop motherboard and still had the same issue.

Thanks for the tip

UPDATE - Intel says 15.x.x drivers with Windows 8 for 62xx and 6300 series are causing issues.

Wonder if they've fixed the BSOD when connecting to a Snapdragon S4 based smartphone running hotspot.

It has a tendency to cause a IRQ_Not_less_than_equal BSOD/kernel panic on quite a few of their recent driver versions

For my 6230, preinstalled Windows 8 drivers are the only working okay for me (dated July 2011).

Do any of you have Linksys routers with the cloud firmware? I had all sorts of wireless issues that I thought were card related. I put on an older non cloud firmware and my wireless issues cleared up. Just a suggestion.

I was having the same problem with the Centrino-N 2230 on a brand new HP laptop. A driver update from Intel at the end of August has appeared to solve the disconnection issues. The updates don't show up through Windows update or HP's update software. I had to go to HP's website to download them manually.

It isn't just Intel, Surface Pro also has this issue. You have to disable N to get a solid connection. Unless Marvell is using Intel Drivers.

I take it very seriously when companies delete forum posts in order to try and play down the issue and silence angry customers. Lots of companies do it and if i find out about it, i refuse to do business with that company anymore.

As of 3 weeks ago, I have been the manager for the Intel Support Communities. Even though I'm new as the manager, I've been a moderator there for years. I want everyone to know that we don't have a policy of deleting posts that make negative comments. I'll remind all of our moderators of the policy and I sincerely apologize for any deleted posts.

So I wonder if this is the same issue I face with the Yoga and its builtin Realtek wifi?
Symptoms: Full bars on b/g/n, cannot connect or get limited connectivity.

Thanks for posting about this (the previous article as well). I had an Intel 6300 adapter and I had these issues no matter which driver I tried. Ended up switching to an Atheros card, which is noticeably slower (even though it says its connected at the same rate), but at least it works all day without connectivity issues.

I've had a few machines at work come in with an Intel 6xxx adapter and they always show this issue after an hour or two, out of the box. I just disable 802.11n and that clears it up. (Slow is better than broken.)

For 802.11ac, going to get a Broadcom card. Never had a problem with those.

Lucky i see this because i've been having this issue on my laptop which has a Intel 6235 adapter. None of the latest drivers fixed the issue. I was starting to think the wifi was broke.

I have the 7260 AC and had to roll back drivers. The latest drivers establish a stable 780-866Mbs connection, only problem, while the connection is stable, actually communication drops all packets every 30 seconds or so, and often you have to reset the adapter.

Rolling back the connectivity fluctuates from 466-866Mbs but it always communicates. Intel just isn't good with Wi-Fi drivers, period.
