Subject: Stuttering when Ethernet Driver active
Posted: 19 September 2014 at 2:45pm
I experience audio pops and crackls when playing a video or general latencies when downloading a file when connected via LAN/Ethernet (I guess not via Wifi cause my Wifi connection is not thaaat fast compared to Ethernet). According to my observations the stuttering only happens when the LAN network driver is somehow busy, which means preloading the video or downloading a file. As soon as the video is chached/loaded or the file is downloaded, the stuttering disappears.
I recently updated the LAN driver due to suddenly occuring BSOD. The update fixed the BSODs but now the stuttering appeared. I already tried to switch to other versions of the driver or even use just the Windows driver, but the problem doesn't disappear.
With updating the LAN driver I also updated all the other drivers (BIOS, Soundcard, PCI, Chipset, etc.) because my system was a little outdated. Everything works fine in games (like Borderlands).
The Graphic card is up to date and running on the latest beta driver from AMD (tried the normal driver too, no difference).
LatencyMon showed me that ndis.sys is causing excessive latency:![]()
Malware Scans are negative with Malwarebytes, Spybot S&D and ADWCleaner.
--------------------------------------------
So as a summary:
The problems started when I updated my drivers! But I can't go back to the state before cause I don't have a backup and the restore points already got overwritten by current ones.
What I updated:
Practically almost everything that was outdated - used SlimDrivers.. maybe wasn't the best choice..
I remember:
- Chipset driver (not 100% sure but a lot of Intel drivers)
- SATA AHCI Controller
- Various system drivers like:
--- Intel(R) 5 Series/3400 Series Chipset Family PCI...
--- Intel(R) 5 Series/3400 Series-Chipsatzfamilie - Thermosubsystem
--- and a few others
- Audio Realtek driver
- PCI-E-Gigabit-Ethernet-Controller Qualcomm Atheros AR8151(NDIS 6.30)
- Broadcom 802.11n-Netzwerkadapter
What I tried so far:
- Try to go back by restore points --> didn't work
- Deinstall virus scanner --> didn't work
- removed all apps from startup --> didn't work
- tried to identify the causing process with process explorer --> the process causing the cpu load was either system or chrome, but chrome not to much (30-40%)
- tried to switch back to the old drivers by installing the vendor drivers from acer --> didn't work but seemed to lessen it a little (maybe)

- rolled back all drivers in device manager --> didn't work
What I found out so far:
- The latency and lags don't appear with Wifi/WLAN --> Just when connected via LAN/Ethernet (maybe just because Wifi isn't that fast, with Ethernet I get 100 Mbit's)
- The latency and lags appeared after the driver updates --> So nothing to do with malware
- The latency and lags are caused when the LAN/Ethernet is busy (downloading, caching/buffering)
