Any suggestions where to find computer networking components such as wireless access points, ethernet cable (250m+) and crimping tool, etc...?

Basement of big C, just past Central on by-pass road. At least 4 shops selling wireless accessories, and there is a big spare parts/components shop at the very right end of basement.

Xnet Computers in Phuket town, on Phang Nga road just opposite the Royal Phuket Hotel (diagonal from Krung Thai Bank). Small shop with many motorbikes parked in front. K. Sataporn is the owner, he also has the Dell shop down the road and two other computer shops. Looks miniscule but that's because mostly do biz with company installations. If K. S not in then ask the staff to have him call; he is on the road much but very good with replying. They have cables etc as well as the hardware. If not on hand will have from BKK the next day.

ok thanks... yes i know the shop in Big C basement... i'm heading to Phuket town today so will check out both places.. thanks
