    I am running 1.0beta11 install. I am really seeing performance issues and wireless drops with window clients.

    Here is the config:

    DSL modem (set to transparent bridging)

    Zeroshell router behind modem – configured to use pppoe.
    wan nic : 63.42.61.44
    lan nic: 192.168.0.3
    DNS enabled
    NAT enabled
    DHCP enabled

    D-link wireless router – configured as ap only.

    I have a windows notebook that connects to ap and then gets DHCP from zeroshell. It will stay connected for about 30 minutes and then drops connection. Renewing ip or releasing does not restore connectivity. Only a reboot. Does anyone have any thoughts what might be causing this?

    Also, my other computers running linux, when accessing web pages paints them slowly. This has never happened until I started using zeroshell for internet access.

    Any thoughts? I am not using captive portal.

    thanks

    I have seen this issue in many manufactures of Wi-Fi equipment. I actually work for one and the first thing I always tell my customers is

    1. For the drop off issue you need to do a few things
    A. update the AP and the laptop. Make sure there isn’t a known issues on the manufacture of the laptops website for that card. (It is a very common problem especially on G cards)
    B. Most all laptops and AP have a log file of what is going on when it gets disconnected. It will tell you exactly what happened when it disconnected

    2. The second thing is to bench mark everything. it will tell you exactly where your bottle neck is.

    Before you start testing everything make sure you test your cables PC to PC to make sure they are good. I have seen many cases where that was the problem!!!!!

    IPERF is a program that you can run on your Linux box and KPERF is a windows version that you can use. You should be able to just Google the two.

    A. laptop to pc going thought just the AP.

    B. pc to pc through the zeroshell with no internet.

    After that you should know where you next step is. I have been testing zeroshell on alot of different devices and rarely find an issue with zeroshell itself.

    Happy hunting 8)

    Your problem could be a couple of things.

    1. The first thing you need to do is benchmark your wireless. Run it in both WPA and OPEN and see what your through put is. You can have a great signal and everything else, but you also could have a bunch of FCS errors. Usually that is caused by overpowering your radio.

    2. I have run into this situation many times. I work for a large wifi manufacture and I have seen it come down to be as simple as being a cable with one strand being loose and causing allot of packet errors. just do a quick bench mark on each of your cables to quickly take them out of the equation

    3. You need to use a network sniffer (on the lan Wireshark is good and Omni peak personal is a basic one for wireless, and both are free) and see what is all being passed around. There could be a bottle neck somewhere on the network and the packets should tell you what is going on.
