Practically every time I see NetGear equipment I have to replace it due to weird problems. At one client someone installed a new 5-port NetGear switch in one department and the whole network went unstable.
One of my larger clients tried a different consultant ("more oriented to a growing company"). When they called me back in to fix the mess I found the 3Com 24-port switch and Linksys 8-port replaced by a 48-port NetGear managed switch. Constant network problems. I put my old 3Com back in and added a second 3Com for 48 ports and all the problems went away.
