wireless problem - EMI?

[frenchi6625]

i have a mikrotik routerboard 532 set up to provide a hotspot solution for a client. everything works fine off site, but as soon as we installed in the new building, ALL, and i mean ALL wireless signal just disappeared.

tried reconfig, diff channels and freq, to no avail. brought in a senao AP to test and the same thing. we even moved the board outside and we could still not connect to the AP. it picks it up maybe 3 or 4 times every half hour but loses it straight away.

moved the whole system back to my office - no problem, it all works. took it to my house - no problem. figured i must have made a config error, redid the whole damn thing, tested it at my office - all good. took it down to the client site, guess what. no signal.

i'm stumped. so is miro.

the site is part of a newly constructed mall, could it be EMI or something? there are no other wifi rigs anywhere close by.

..even off the RB on site?

Yea, don't ya just love that 'I *know* I've done it right but it still won't work" losing-your-mind-feeling...?

Which branch?

Well, for my part I'd get stumble logs/screenshots offsite (obviously a notebook is best here, on account of needing to do this off- and onsite) and repeat same at yon mall. You could also 'stumble' around the mall to crosscheck your 'known' condition of thenre being no other wi-fi around.

Failing that (and I REALLY want one of these toys!) I'd consider investing in verrrry nifty spectrum analyser that I reckon is tailor made for getting to the bottom of this one.
