Dneska som bol premeravat jednu lokalitu a zistil som ze mi z APciek ide velmi slavy signal.. cca 30m od APcka nameriam cca -87dB co je bieda na to ze tam mam 10dB sektor + 2m kablu. Skusal som aj nastavit max. vykon ale ziadna zmena... mam v tom robcku osadene 4 Atherosy, 2xCM9 a 2xTP-Link
Ked dam scanovat pasmo, tak mi na tych TP-Linkoch nascanuje siete vzdialene 20km ale ked scanujem z bodu cca 3km odtial, tak nenajdem ani naznak po tychto TP-Linkoch. Mam podozrenie na slaby zdroj. Mam tam 30W 18V (1.7A) trafko. Moze to robit toto? Alebo mam skor hladat chybu v tych TP-Linkoch? Ale to by zasa znamenalo ze mam 2 kusy s rovnakou vadou...
Co si o tom myslite?
Nerad by som vymienal karty pokial je chyba len v zdroji... |

| Nemyslim si, ze je to vada kariet. Mne sa to stalo po 2dnoch intenzivnych buriek, postupne stracala vykon, nakoniec som mal problem napojit sa na 10m |

| ale mne neodchadzaju postupne... oni takto funguju od zalozenia do RBcka... rx funguje bez problemov ale tx ma problemy... problem nie je v tom zeby sa postupne stracal signal... signal je rovnaky, ci nastavim vystup na 7dB alebo na 17dB (aspon tak sa mi to v netstumbleri javilo) |

jaj.. no to moze byt.. ale nie vsetky TP-Linky, asi iba tie lacne WN-650G, lebo na inom bode mam WN-562AG v daughterboarde a ide bez problemov...
pomoze ak prehodim tie 2 TP-Linky z DB na dosku a CM9 dam do DB? |
