I've recently bought a Lenovo Y700-15 laptop, with Intel Dual Band Wireless-AC 8260 in it, and since beginning, i have a lot of wireless connection issues.
I've tried many settings, reinstalling drivers, updating them (i have latest 188.8.131.52.1 version), and nothing really works.
The problem is, that whenever im trying to do something, like using internet, playing online games, watching videos, a connection between me and router is becoming unstable. And by that i mean frequent in-game disconnects, freezing website loading, high ingame latency (even 10k ms). Pinging router without doing antything is fine - it stays at 1-4ms, but when im playing/watching/whatever, it jumps to 400-1000ms, with request time out errors sometimes. Only i have a problem like that - there's a console in my house, second laptop, and none of them has a problem. Even on my old laptop i didn't had that problem, so it must be a problem with a wireless card.
What i've tried so far:
1. Reinstalling drivers/uninstalling them/updating to latest version;
2. Wireless card is on maximum performance in power-saving settings;
3. Tried diffrent connections like a/b/g;
4. Tried diffrent settings, diffrent channels;
Because i've tried everything that google had to tell me, and it's still not working, and i can't figure it out by myself, im asking here, and i'll be glad if you can help me solve that.
Wireless connectivity involves different factors, here are some things to check from the side of the adapter and the PC:
- Consider the recommendations from the advisory "Troubleshooting Tips for Intel® Wireless Technology" regarding issue isolation and driver updates.
- Apply the Recommended Settings for 802.11n Connectivity:
- Try disabling the Bluetooth* component of your system and check if this helps. Bluetooth* can cause signal interference and is normally disabled with a switch in the PC chassis, or a key combination. It can also be done by disabling the Bluetooth Radio in Windows* Device Manager.
If the issue persists, we will need to get more information about the problem, for this you can download and run Intel® System Support Utility, then use the tool to create a full report, save the file and attach it to the thread using the Advanced Editor.
I've attached a file you requested. I've disabled bluetooth adapter, used recommended settings you gave me, but, still problem persists. I went with laptop to my girlfriend house, to check, if on diffrent router i'll have the same problem. And still, nothing really changed. I've pinged router first - everything was fine. But when i've tried to launch an online game/load some youtube video, connection between laptop-router became again unstable - request time out, high latency etc. And i have no idea what causes the problem.
The log you provided shows that the adapter is using Channel 3 of the 2.4 GHZ band. However, it is getting signal strength of 68%, which may cause connectivity issues.
Since you already set the power options for wireless maximum performance when plugged in and on battery, and also disabled Bluetooth, there are few additional actions to try. Set the following properties for the adapter in Device Manager:
802.11n channel width for band 2.4: 20 MHz only
HT mode: HT (supports 802.11n compatibility)
Throughput enhancement: Disabled
- If the issue persists, try placing the computer close to the Access Point and check if the behavior changes.
- Look for possible sources of interference that may be affecting the signal strength.
- Try using a different wireless channel, or connect to a 5 GHz network.
Hi, thanks for your response!
Again, i did everything as you said. Tried diffrent channels, i switched to 5ghz, etc., but still, none of that solution worked. Still im loosing packets.
- http://imgur.com/a/nlAw0 Imgur: The most awesome images on the Internet <- theese are pinging result after launching a game, and before. ( 7% loss on 120sec. ping is when im doing something, like i said).
Maximum ping depends on nothing, sometimes it's even around ~3000ms.
I've borrowed plug-in USB wireless adapter, to check, if it'll work. And it's working without any problems, flawless pings, no disconnects, 0 lost packets. And that things is much, much older than built-in wireless adapter.
Have you got any diffrent solutions in mind? I would be grateful, thanks in advance.
Make sure that the Access Point is using the most recent firmware for it, and if possible, test the connection with a newer router.
If the connectivity issue persists after optimizing the configuration, testing different routers and networks (2.4 and 5 GHz), and with the PC close to the Access Point; we would advise you to check with the Computer Manufacturer Support, they will be able to check for possible hardware issues (loose antennas, faulty hardware, etc.):
Feel free to let us know any change in the behavior after checking the access point, or with the PC manufacturer support. Or in case you have any further questions about this.
