Re: [Karlnet] RG-1100 power input

Bob,

They had various problems, the caps fixed most of them. I have a Macintosh 
as well and using it, I can reflash the firmware very easily.  A lot of the 
time the firmware is corrupted as well.  I think out of 50 or so I only had 
1 or two that the caps would not fix along with the firmware update.  I 
always update the firmware and test them as 802.11b before flashing them to 
KN. I have had very good service with the Airports using this method. One 
note of caution. If the Airports have the standard brown colored caps (there 
are 2 of them), then they should be replaced. If the caps are green and some 
other color (I don't remember what) then they have been upgraded by Apple 
and are usually ok.  A tell tail sign of problems is if the top of the cap 
is BULGED out any at all, they are going bad.  Again, if they are brown, 
they WILL go bad even if not bulged out. The problem stems from the heat 
rating of the standard brown caps. I use caps I purchase from Digi-Key. 
Part number P10273-ND  330uf 25vdc rated. I use the same cap for both input 
and output positions. You can order on-line from Digi-Key.

If you have some that you cannot get flashed, send them to me and I will do 
it for free (for a few anyway). Just have the caps installed first. Or I can 
change them for a small fee. I have plenty of caps in stock. email off-list: 
steve@vroomwireless.com or loomiss@cox.net .
