My PC has an integrated AC-9560 (Gigabyte Z390 Pro Wifi motherboard), and am running Windows 10.
After being connected to the wireless network for a while (especially with sustained network file transfers) the wifi connection icon in the tray will have a yellow exclamation point and will say that the network has no internet access (still connected to the local network - but cannot access the internet). Disconnecting and reconnecting from the AP doesn't help.
While this PC is having issues, other devices including phones, tablets, other PCs with Intel 7260 wifi cards (running Win 7) can all still connect to the network and access the internet fine. Even on the same computer if I switch to a USB wifi adapter on the Realtek chipset it works fine.
I have tried deleting and reinstalling the drivers, updating to the latest drivers (20.120), downgrading to the most recent drivers on the Gigabyte site (22.214.171.124). This happens on both 5GHz and 2.4GHz bands.
Any help will be appreciated - I'm tearing my hair out.
Hi David - Thanks for your reply.
Have tried it , but unfortunately the problem persists.
After resetting it functions as normal (network and internet connectivity) but after some sustained network load the yellow exclamation mark appears again.
Again, if I switch to using a USB wireless adapter (on the same PC) it is able to maintain continuous connectivity even under sustained loads.
Another thing I noticed is that if it comes up with the exclamation mark while connected to my 5GHz network, I can switch over to the 2.4GHz and it will work for a time too before the mark appears on my 2.4GHz network as well.
Any other ideas?
Thanks. Tried that...unfortunately still no dice - 5GHz still drops internet connectivity after a while.
However 2.4GHz might be ok (so far its stayed fully connected for longer than the 5GHz did..but it's only been a few hours.)
I've only been using 2.4 since my last post - 2.4 seems to be working stably - no dropouts since.
Have just had a look at the recommended AC settings, the current settings on my PC match those given on the page.
Will switch to AC and report back.
Since the last posts I remembered something similar happening quite a while ago on a laptop which had the Intel 5100AGN Wifi card.
Basically if I hibernated a few times time (eg using it for a week with only hibernating each day rather than shutting down) when I turned it on it would either be unable to connect to Wifi, connect with "no internet", or connect and drop out shortly after.
For the past week and a half I've been shutting down my PC each day rather than hibernating and so far haven't experienced any of the previous drop out issues except for once where I put it to sleep a few times in a 3 day period.
I also checked local network connectivity when it does drop out - although it says local network no internet, local network isn't accessible.
Is there anything else I should be checking/trying in light of this extra information?
I would be interested to see if there was a final solution with this.
I have the same issue with the same wifi card in my Razer Blad 15.
I have only had the laptop for a month or so and have been going crazy with this issue.
I have tried many many solutions with no avail.
The connection seems to just come back after a while and no solution ever seems to work more than once.
I have a wifi mesh network but no other device in my house has any issues including my previous laptop.
It used to fix the issue if I connected to a different wifi extender which did not even have internet access and connect back to my normal network but that stopped working after a while.
Connecting a usb wifi reciever and unplugging it seems to fix the issue but it will drop out again in the next day or so.
I am at the point where I am considering replacing the wifi card myself as I do not have the luxury of sending my machine out anywhere which I use for work.
Any help or updates would be appreciated as this is the only place online I have found someone with the same issue.
I have an Intel AC-9260, with the exact same problem. I use both 2.4 and 5 GHz, same problem on either one. Settings are fine, no other devices in the house have this issue.
This is an old thread, but I bought my AC-9260 last week, and was having the identical issue. It seems to be resolved by setting MIMO Power Save to "No SMPS" in Advanced driver settings.
MIMO power save mode
MIMO power save mode, also known as spatial multiplexing power save (SMPS) mode, allows the client to save power by keeping one antenna in a receive idle state.
|Note||Some legacy APs may have compatibility issue with supporting the SMPS mode and may cause various link quality problems such as low throughput. Change this setting to No SMPS may help to work around the issue|
