I was wondering if it is safe to upgrade the firmware of my DIR-655 A4 with the software on the dlink website (http://www.dlink.ca/products/?tab=3&pid=DIR-655&rev=DIR-655). It only shows firmware for the "DIR-655" and "DIR-655_REVB", so I was wondering if the A4 fell under the regular DIR-655 category since the firmware on there goes up to 3.0 and my own firmware is only at 1.34NA. (I've read some people are using 1.36NA? - Do I need to find that somewhere; and will it improve my connection quality? I seem to have a lot of small lag spikes and have already messed with all the settings (channels are fine, wireless is set to mixed g & n, etc etc)).
Thanks in advance!
