I started a thread the other day and found out about this router - it sounds very impressive (time to order mine tomorrow!).

One thing I must advise of, as a communications engineer, of sorts (well, radio engineer - one-way rather than two-way!), is that the legal limit for output of any unlicensed device on the 2.4GHz band is 100mW ERP (that's not 100mW set in the firmware, it's 100mW including the gain of the antenna, which will typically be 2.5dB - making the legal limit for router output power, set in the firmware, around 60mW). Now, whether you run more than this is down to you - it's not such a problem in less urban areas. However, if you're in a big city, just make sure there are plenty of other free channels which others can use.

The problem for oj123 is that the linked antenna and the supplied antenna is omni-directional around the antenna itself - very little signal 'leaks' out below the antenna to the floor below. The other problem is that signals around 2.4GHz don't do too well at going through solid objects!

I'd first try raising the output power of the router, and then perhaps investing in a new aerial if the first option doesn't work. What I'd also try is leaving one of the two aerial vertical and putting the second horizontal - this will direct a good quarter of the signal through the floor and downstairs.

Oooh, I have a question of my own - I'm planning on getting this router from eBuyer (http://www.ebuyer.com/customer/produ...duct_uid=63763) - now, for DD-WRT to work, I need "Linksys WRT54GS v1.0, v1.1, v2.0, v2.1, v3.0, v4.0 - not v5.0"... anyone know which version this is?
