Before I thought I'd lost the router I bought on Ebay, I bought a same model of router off the computer shop. But to my surprise, it's arrived finally. The first class delivery took 10 days even.
Anyway, I've got two same routers.
After some consideration, I decided to use both of them to build my home network.
When I finally got every thing done, I felt that what I learned in the school has some really practical use.
A bit of achievement, a bit expensive.
