touch pad is jerky on one network works fine on another network
The touchpad on my Dell Latitude E6410 laptop works fine at home but is jerky at the office. The only difference I can think of is different wireless networks. Both networks are on Suddenlink and use the same model router: TP-Link TL-WR841N. The IP of the home network is 192.168.0.xxx and at work is 192.168.1.xxx The touchpad driver is Dell (ALPS) v 8.1200.101.127. The Dell website and Windows update state it is up to date.
Any ideas for this weird problem?
Thanks

Do you connect any USB drive or anything to your PC at work ?
if your answer is no,
Then I think the router firewall settings at the office can be the cause of this problem.

Check if other PCs at the office have similar problem,
Disable your Windows firewall when you are at office and check for any changes.

Only one other computer at the office - tablet, no touch pad.
The network should be irrelevant. Now the question is by the time you get to the office, has the laptop been on (when I say on, I'm including that it's been in hibernation) for a while? Try rebooting it and see if the problem goes away. I have a Dell Precision laptop where the touchpad gets weird after being on for quite a while, but it clears up as soon as it's rebooted.

I have rebooted the laptop many times at the office and the touchpad is still jerky. I put the laptop on standby, go home, come out of standby and the touchpad is smooth.
I know the network should be irrelevant but I can't think of anything else that would be different. Both at work and at home, I use 2 different power supplies (4 different power supplies total.) Also I use the laptop on battery at both places. In all cases, the touchpad is jerky at the office and smooth at home.

Have you tested at work without being on the wireless? Try using a wired connection, as well as not being online at all.
Since you're looking at the network factor.... check to see if both routers have the same firmware version. If needed, update the firmware on the work router.

Both locations use the same model router: TP-Link TL-WR841N with the same firmware. I turned off the laptop wireless while at home and the touchpad is smooth. I will try turning off the wireless when I am at the office tomorrow.

I am at the office now. The touchpad was jerky until I turned off the internal wireless card when the touchpad smoothed out and remained smooth after I turned the wireless card back on. If it remains smooth, then I may have found a temporary solution and will try changing the network IP address in the near future to see if that helps.

Ok, not the wireless, it looks like it is the two power supplies I use at the office.

It was the power supplies at the office.
