Freezing Mouse Pointer

Since purchasing a few summers ago I have been plagued by a freezing mouse pointer on my Thinkpad T400 laptop. The mouse is a generic wireless.

The freeze I experienced is during disk operations. Moving the pointer is much like pushing strings. Within a couple of seconds the pointer returns to normal.

At least I thought the problem was disk operations. After suffering this problem I happened to stumble across what likely is the root cause. Disk operations was a mask to the actual root cause. I did not discover this until I created an iperf script to run as a cron job on my LAN. Nothing fancy. I only wanted to monitor basic connectivity.

Running iperf (old version) all but stopped the mouse pointer. While iperf supports using a file to test drive I/O impact (-F, --fileinput), I am not using that feature.

I saw the problem only on the laptop. Other than maintenance I use wireless with the laptop.

Could the laptop wireless be interfering with the mouse?

Apparently.

I changed the channel in the wireless configuration of my router from the default channel 6 to channel 7. I moved the mouse USB adapter to the other side of the laptop.

No more stalling or stuttering.
