i asked this on a fairly regional linux user group list about a week ago and didn't get any hardware recommendations. i figured i'd ask here for a wider net. here is the thread i started last week: http://calypso.tux.org/pipermail/novalug/2012-October/033546.html
what i want is a usb wifi card that can connect to multiple accesspoints at the same time. i've been told this would be slow - i only need this to do ~100kbps (12.5k - i'm guessing 84k voip + vpn overhead) for voip traffic inside a vpn tunnel (anything else is bonus). after some googling (actually, google was useless and it was mainly duckduckgo) i found that the madwifi driver supported up to 4 virtual interfaces to be used as access points. then i found documentation that said it was now integrated into the kernel and supported by the ath5k and ath9k drivers. i was never able to find someone that had used one card to connect to more than one access point though. so, is this the technology i'm looking for if i want to connect to multiple access points at once? is this only supported by the two atheros chipsets or are there other cards that support this? any recommendations on a usb card for the job? everything else being equal, the smaller the better. if i can't find a card that can connect to two networks, i'm thinking of getting an unpowered usb hub (probably this: Targus ACH74US Ultra Mini USB 2.0 4-Port Hub) and then get two Edimax EW-7811Un. if i have to go this route, any idea if i can run two wireless cards off of an unpowered usb hub? how badly will two wireless cards right by each other interfere with each other? i'm guessing a cm of separation should be enough? should the cards be 90* to each other or would 180* work as well (i don't know how directional and which way antennas in those usb cards are) ? note: i'm aware there is a voip protocol for hopping between networks called vcc. this needs to be enabled on the infrastructure and i want to jump across networks that i won't own and maintain a call. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
