    EDITED :

    My story is quite complicated, but I'll try to show only the most important matters. :roll:

    Network :
    1. my neighbour no1, who's client of internet service and in his computer is connected wired to router in his house.
    2.my neighbour no2 has wireless connection to the AP.
    3. Me, I've got wireless connection too.
    We both have got D-Link DWL-G520+ cards (chip TI ACX111).

    MY ROLE : I'm administator of this network :guns:

    I changed firmware of my WRT from tofu13c to Thibor15c a week ago . Also I set WEP encryption, instead of WPA-PSK , because on my gentoo linux, wpa_supplicant doesn't support acx111 opendriver (D-Link card).
    I met my neighbour no2 , who told me that his internet connection is veeery slow.
    So I went to him and it turned out that he had connected to the other network, which was completely unsecured :rofl:
    I helped him to connect to ours. The next day he claimed me that he can't keep the connection with AP more than few minutes, then breaks. I started tracking DeviceList through webinterface. That was true, after 8-9 minutes my neigh' was disconnected and then his DHCP lease renewed with new connection.

    SETTINGS : DHCP is on, with static assigning IP by MAC, there's allowed only 3 clients with adresses : (no1) .

    He got the idea to connect once more to that unsecure network. There everything was working fine there, he said. I was confused.
    My neighbour no2 said me that he heard that the order of IPs has meaning in priority of clients.
    I agreed with him , but it's visible in a huge network with about 100 clients, not in small like this one.
    Finally I did his request and now he's got However....after that he couldn't have connected !!! Argh.....
    Recently, I've returned to WPA-PSK. It doesn't helped, but....
    my "smart" no2 rebooted his PC, and then... it connected !!!!!!
    And "baby" keeps it. :eek:

    What was that , people ???? I'm planning set WEP again, but my neighbour is pretty sure, that was my fault, not his computer. How it's possible ? We've got identical wlan cards, settings are the same (I've checked).
    Any suggestions are very welcome.

    Some news in case...

    I've changed encryption to WEP again and now I've got the same trouble as my neighbour had. Sometimes it breaks connection, sometimes it's only DHCP renewal in period of 3 minutes !!! (one day is set) .

    EDIT :
    Works fine after the change of driver. But still don't know what about my neighbour no2.

    ->There's also another strange thing....
    If I set in my AP WEP Default key number 3.
    and the key number in driver properties of my card also set 3 I can't connect .
    But it works fine set 1 in cards properties (although I use the3rd key).

    the best solution to you problem is two fold.

    Your first problem was caused by your linux "wpa_supplicant driver" not supporting the D-Link card. now you have messed the whole network up simply because of you letting the card drivers dictate your method.

    My first suggestion is use a Card that supports linux and WPA, or get a driver that works with it. then go back to you original WPA setup.

    My second suggestion, and please dont take this the wrong way, either learn better english or get someone else who knows it better than you to post this message. I did not understand at least 80% of it.

    PS. what is the thread topic meant to be?

    f.... magic.... ??????????????????????????????????

    Sorry for my poor english... I'll try to correct it.
    EDIT : I'm truly sorry... I was very tired and frustraded, when I was writting ths.

    f is first letter of "f%#ked" (sorry , vulgar word)
    magic <- i have no idea why it happens

    It's not so simply, I can buy a card besed on ralink or atheros chipset...but now I have no money for this.
    It's not the main matter. It should work fine as it did on original Linksys firmware.

    All in all, I've noticed that on linux all works, so I've gone back to previous, more stable driver on WindowsXP. However, I don't know if it works on my neighbour (he'll be back tommorow).
    Once more, forgive me the mess I've done.

    no problems.

    if your happy with the setup on the router then move to the wireless clients and sort them out one by one.

    Ok, now is set Open WEP with 1st default Key and all clients work fine <confused>.
    The only one difference since the problem appeared is the IP adress of one trouble-making client is now

    Does it have anything to do with this change ?

    does this .99 have a fixed IP address or static ip address? does the router assign the IP or The PC itself?

    now : (no1)

    did you change your DHCP range on the router? or are you assigning IP by MAC?
  10. lol24h

    lol24h Network Guru Member

    Am I writing so unreadable ?? Look at my post.
    YES, I'm assigning IP by MAC.
    Previously I set the DHCP Range starts at :
    now is set :
    and the Maximum Number Of Clients is still 3.

    yahhh.... i hit reply and walked away from my PC, by the time i came back and hit send you already replied. :)

    "My neighbour no2 said me that he heard that the order of IPs has meaning in priority of clients."

    IP address has nothing to do with priority (both connecting and actual bandwidth priority). Your only priority settings are going to be in QOS.

    I assume you have changed wireless channels (maybe even a site survey so you know what channels are cleanest) as well as remove all encryption? If not try removing all encryption and if you dont have problems its all in the security settings/PC driver.

    Another thing is you could save your config and reset to factory defaults and then re-configure without IP by MAC
