Be aware the home routers often struggle to handle the large number of
connections that tor relays create. In **worst case** scenario you will
have to reboot it every hour, best case every three / four weeks.

Generally speaking most home routers would be able to handle <10MBs of tor
traffic with some capacity left over for maybe two PC's web surfing /
YouTube etc depending on your broadband speed.

For some perspective, I experimented with installing OpenWRT on medium-old
"high end" router, the interface informed me it could support up to 16000
simultaneous TCP connections. Fair enough however the gigabit Ethernet
maxed the routers poxy 600mhz single core processor 80mbits

If you are using Wifi and have poor signal (far away from router,
interference from nearby Wifis etc) this will obviously impact your relay.
If your netbook does not have a Ethernet connection consider buying a USB
to Ethernet device.

Thanks.
