Хубаво де, ама похвали се както трябва - дай инфо за устройството и конфигурацията.

3com pci a/b/g, linux

Засега не бачка на големи разстояния, но сегашното ми трасе е под километър, така че няма проблем:)

Ми че то 1km си е огромно разстояние бе.

Кажи какви скорости развиваш ?

Е огромно 1 Км.... айде сега .... Абе каквото и да си говорим 3 com e 3 com.Ако кажеш сега и какви пари е :)) и с какви антени си го пуснал :) иначе от това което си постнал си е направо като ЛАН :) аз мойте ги докарвам почти винаги под 10 мс :) ама не и с такива огормни пакети да са меткат :).Искам и аз такова :))

3com винаги е №1!!! Тва е положението.

Не мисля, че заслугата е на 3com, по скоро на Atheros.

Единственото, което 3com са направили, е че ме накараха да ровя по сорса на драйвера, за да им подкарам платката, щото си имат собствено виждане по въпроса за PCI ID-тата. А като цяло поне досега по отношение на wireless продуктите 3com са си направо зле, но забелязвам, че се раздвижват.

Цената и скоростта съм ги посочил още в първия си постинг. Антените не знам как да ги опиша, идват комплект с Proxim MP11, но в Елкостар правят.
