I live in a tourist area in Vietnam with too many free wireless routers in use giving a lot of interference. There are about 20 hotels/guest houses visible from my window. I have a desktop computer which currently has a crappy USB WIFI g modem with a 3 inch antenna. This usually works but 5-10 times a day I lose signal for 1-3 minutes.
The question is would it be helpful to get a router and use that as my client adapter? Bigger antennas would enable stronger reception to nearer access points, but maybe receive more interference from other routers.
The local computer stores have a very limited selection of routers. Only 2 are simultaneous dual mode: D-Link DIR-825 and linksys WRT610n. I figure having the extra band available could not hurt. These routers both give GigE Ethernet switches which would be useful.
When using a router as a client adapter, does it work in a way similar to Windows when connecting? i.e. Will it connect automatically to a set of routers that I have authorized? All the FAQ's I have read indicate the router must be configured to use a specific SSID. Different restaurants and hotels have their routers turn off at night or the staff wants to recharge their phone so it may be unplugged.. I do not want to be tied to a specific router.
I have done Unix development and am very familiar with TCP/IP so DD-WRT does not scare me.
Last choice: Perhaps a WI FI adapter with a better/removable antenna: Wireless-N PCI Adapter with Dual-Band (WMP600N) * High-speed dual-band Wireless-N networking for your desktop PCs. * Operates in the 2.4 and 5GHz radio bands -- choose the one with least congestion in your area.
I may move to a house, in which case the router would be used with a DSL connection The WI FI adapter would then be useless. A little extra money now for a more versatile device would be worth it to me.
