I've seen a few examples on how to boost the wifi signal on my router. All show the default TX Power at 70, however mine is only currently set to 30. What would be the best (safest) I could raise this number to? Thanks for any help.

the transmission power is limited by the regulatory domain
the maximum is 30dB / 1W depending on country and frequency range


So you can set whatever you want, the AP doesn't send more than 30dB anyway

In addition, the pure transmission power does not have much effect on the AP side, for good transmission rates you also need a client with good antennas

I am not sure if this still is the case, but I noticed on BCM routers that the defaults were set very low and that you would have to enter 999 [mW] to have the router broadcast at the full TX power. There was a bug that would not allow you to enter the full 4digits to yield 1000...not sure if that got fixed or not...

For the marvell stuff...Not sure how the gui shows power but it seems in mW and not dBm like for atheros; regardless, it seems awfully low if it's showing 70mW and you can bump both radios to 999mW safely without any worry (or 1000 if the bug got fixed).

On the other note- To ho1Aetoo's point...the best routers can go up to 36dBm (3981mW) but have to be attenuated by the antenna to 30dBM (1000mW). While the best wifi cards/clients, AFAIK, hit about 21-24dBM back to the router...and most are 18dBm at VHT80 peak MCS rates- so to his point, it will be the client that shits the bed first everytime by dropping the signal.
