My wife has the same usb netgear network adapter as first poster. Web protection caused the bad pool error and crash on the first none beta release of mban 3.0 it was then fixed in the next version and can confirm the issue is back again on last weeks 1075 build.
Also noticed before the crashes that sites like youtube and bbc will not load, some do. DNS issue caused by mban?
Like when the problem happened before disabling web protection does resolve the crashes and websites being unreachable.
5 other machines i run mban 3 on are functioning fine on latest build.
All machines on either win 10 home or pro 64 bit
