how/why are you giving access to unknown people on a network, whos PCs you cant access, to your modem??? i cant figure it out... are you flatmates sharing a single connection? how many users? or is it a measly 128kbps connection shared throughout an entire building/colony??? 🙂if the modem is yours/under your control, simply unplug it from the "network" and directly plug it in to your PC only... the other users will suffer downtime while you are browsing...
