Constant network drops/reconnects with Malwarebytes

CodeRogue · 10-26-2016, 02:00 PM

Using a Toshiba Tecra Z400t-C - Skylake
Intel Core i5-6300U CPU@ 2.40GHz
Bios version 5.70 (Date 5/31/2016)
SMBIOS Version 2.8
Running Windows 10 Pro 64-bit OS (Build 10586)
Using the latest (as of this post) DisplayLink software

This laptop is connected to a Toshiba branded DisplayLink 4K.
With a Microsoft USB Mouse and Keyboard, ViewSonic VG2439m monitor, and network
hardwired. (currently have wireless network turned off)

When the network connection is used through the DisplayLink 4K, there are constant
network drops/reconnects.

If I unplug the network cable from the back of the DisplayLink 4K, and plug it directly into
the laptop, this network connection remains solid.

I have reboot the laptop several times which "appears" to resolve the issue for awhile

Is this a know issue, anyone experiencing the same/similar issue, and any suggestions
to resolve this?

Thanks a ton!

I have the exact same issue. Dell Inspiron 15, 7000 series. Also slow screen update, if I minimize a window, the space remains blank underneith, or the content of the previous windows stays behind. Terrible. Did not notice the slow screen update that much before Windows 10 anniversary update (build 14383). I have the latest drivers for displaylink (released 25.10.2016).

I'm having a similar issue. Displaylink Driver 8.0 M3 seems to be causing ethernet drops. I can go for about 3 hours or so, and then lose connectivity. Usually a reboot fixes it, but today, I could only get my ethernet back by powering my Targus dock. I have two HP laptops using Windows 7 Pro and both are experiencing this. If I switch to WiFi, I have no problem.

I'm thinking it may be a good idea to roll back to 8.0 M2. Is that possible? If so, what would be the best way to do that?

I have decided to give up on using my Targus dock's ethernet port. No matter what I do, I keep getting random internet disconnects. When I check my connection status, it says my ethernet cable is unplugged, but it isn't. No amount of wiggling makes any difference. So I have just moved my cable to my laptop's ethernet port. Much more reliable.

UPDATE: Found out my BIOS was outdated. So I updated that and then used the DisplayLink Cleaner utility to uninstall my DisplayLink drivers. Then I downloaded and installed a fresh copy the latest DisplayLink Driver and so far, no dropouts on my ethernet connection. If something changes, I'll post back. Right now, I really think I may have had a corrupted DisplayLink install. I don't think the BIOS really had much to do with this.
