I'm new to this forum and might Need some advise for setting up WLAN connections using my Intel WLAN card.
I'm using WLAN connections to synchronise data between my professional notebook (Intel Sandybrigde with Intel 6205) and my personal notebook (AMD K8 with Realtek 8192se card), and further to backup the data from the personal notebook to two different servers also via WLAN.
As my professional notebook has an Intel 6205 WLAN card build inside, I can use Intel My Wifi to make the WLAN card become an access point. I've known that for a longer time and had already bought a second Intel 6205 card because of that feature, to build it into one of my servers.
While using my Wifi the first time for synchronising data last week (the professional notebooks Intel 6205 card worked as access point with Intel my Wifi), the connexion broke and I got an error in Windows. It said, the network resource isn't available any more.
As basic test I did some pinging (via Windows console using the ping command). After a longer connexion duration (several minutes) I get a lot lost packets, about 12,5 %!
My first suspect was the cheap Realtek card in my personal notebook, so I bought another WLAN card from Broadcom. I tested the connexion to the professionals notebook Intel 6205, with the latter working as a “My Wifi” hotspot, using all three available cards in my personal Notebook:
- Realtek 8192se two antennas – about 12,5 % lost packets
- another Intel 6205 two antennas – no lost packets
- Broadcom BCM4313 two antennas -- far more than 50 % lost packets -, most times they can't connect at all
The connexion between the Intel My Wifi Hotspot and the Broadcom BCM4313 works only reliable (without significant packet loss), when setting the Intel 6205 card into 802.11g mode. But with this restriction I get only about 20 MBit/s throughput, contrary to the already slow 40 Mbit/s between two Intel 6205 cards. This is somewhat '2003-standard', but not a contemporary performance. Is there some other kind of fix for this? I also can't
say the My Wifi Software to use 40 MHz channels or to work in the 5 GHz spectral range.
I have also another, maybe a minor problem with the Intel 6205 card. Connecting it to my DSL-router I get constantly about 0,5 % packet loss, connecting it to an Alfa AWUS036NH adapter (working in hotspot-mode) gives the same 0,5 % packet loss. I don't have this kind of packet loss with my other WLAN-cards from Realtek and Broadcom. By the way, also in this situation the Intel card is significantly slower than the realtek card, but equal to Broadcom's performance.
Are there some driver tricks to get a reliable 802.11n use with the Intel 6205 card? In fact My Wifi was the feature, for which I purchased this card.
