You could have them 2 inches a part and the rb411 gets eth port whacked every time while the RB532 - and anything else in your inventory keeps on ticking. It is a board weakness even though I don't have the understanding of electronics you guys do. I can't fix em but I can tell you the difference after a bolt of lightning :) (no matter how its installed - grounded etc) Scott Carullo Brevard Wireless 321-205-1100 x102 -------- Original Message -------- > From: "Dennis Burgess" <[email protected]> > Sent: Monday, August 03, 2009 11:45 PM > To: "WISPA General List" <[email protected]> > Subject: Re: [WISPA] Defective Microtik > > Same here, installation is key!
