    Wireless laptop connectivity


    Cant really find a great way to describe my problem by topic alone.. but i have some weird problems with my 2 laptops running windows 7 x86.

    Now.. My setup is basically like this:

    Wireless router connected to my adsl modem from one of the LAN ports on the router (Basically working as a AP only.. No nat/firewall++)

    I have 3 desktop computers connected to the lan ports on my adsl modem.

    All computers get DHCP adresses from the ADSL modem, and are all set up to the same workgroup. I have tried the "homegroup" thingy, but that is only working until next reboot (as the laptop will be unavailable from the desktop computers).

    All 3 desktop computers can connect/share files between them. I can ping all 3 desktop computers from eachother. I can ping all 3 desktop computers from my laptops. All 5 computers can connect to the internet without problems.

    However, i can not connect from any of the desktop computers TO the laptops. Ive set up filesharing on the laptops, and i cannot connect directly from a desktop computer (wired) to the laptop (wireless). Now.. this would be easy if it was ONLY that.. but here is the twist :

    I can access/ping/whatever TO the wireless computer if i FIRST connect FROM the wireless TO the desktop!

    Meaning.. To access a share on the laptop, i first have to connect FROM the laptop to a share on my desktop.. and THEN i can access the laptop from my desktop just fine.

    The same goes for normal ping.. Ie. if i ping the laptop FROM the desktop, i get request timeout. If i ping the desktop FROM the laptop first, and THEN ping the laptop FROM the desktop, it works fine.

    I have ofc disabled firewall, i have NOD32 antivirus installed witch have no known firewall or filtering. (I also have tried disabling this).

    Now.. this could be a basic wireless configuration setting on the AP itself, but if i boot the wireless laptop on eg. a ubuntu livecd, i can ping both ways with no restrictions at all!

    Any ideas? Both the laptops are of different manufacturer.. one is a 2 year old Compaq pressario v6502EO, and the other is a brand new Acer Aspire.

    Can you provide ipconfig /all detail of one desktop, and of one laptop?

    I have ofc tested without ipv6 enabled with absolutely no effect on my problem. (Default boot from the ubuntu livecd also enables ipv6 on my adapter, so i would not believe this to be the direct culprit).

    192.168.0.1 is the adress of my ADSL router.

    Comparing the desktop's LAN ipconfig and laptop's wireless LAN ipconfig, i can't see any reasons for all the machines to connect to to the other. If the other machine's ip details are consistent with these, then you got a perfect network. All able to surf the net compliments this.

    As for,
    However, i can not connect from any of the desktop computers TO the laptops
    Seems to be a share permission or credentials issue. How do you do your connection to the shares and what credentials are u using?

    If it was "only" this, i would agree with you, but afaik there should be no credentials needed to do a normal ping.

    And as i describe above, if i connect FROM "lap" TO "Game", it works with no problem, and i can connect FROM "Game" to "Lap". However, if i try to do it the other way around, i only get an error with the computer not found.

    Code:
    Pinging lap.workgroup [192.168.0.13] with 32 bytes of data:
    Reply from 192.168.0.30: Destination host unreachable.
    Reply from 192.168.0.30: Destination host unreachable.
    Reply from 192.168.0.30: Destination host unreachable.
    Reply from 192.168.0.30: Destination host unreachable.
    
    Ping statistics for 192.168.0.13:
        Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Is what i get when i try to ping the laptop from the desktop.

    After doing a ping Game from the laptop, this is the result:
    Code:
    Pinging lap.workgroup [192.168.0.13] with 32 bytes of data:
    Reply from 192.168.0.13: bytes=32 time=1ms TTL=128
    Reply from 192.168.0.13: bytes=32 time=2ms TTL=128

    Reply from 192.168.0.13: bytes=32 time=1ms TTL=128
    
    Ping statistics for 192.168.0.13:
        Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
        Minimum = 1ms, Maximum = 2ms, Average = 1ms
    This last for.. well.. about 2-5 minutes if i do not continue any traffic between the two computers. Then its just like the wireless disappears. (Surfing/whatever works fine all the time, its the connection between the two computers that stops).

    I am not able to ping the other laptop from "Lap" at all.. nor the other way around (since they are both on the wirless ap).

    Fun times eh? :P

    Now.. a small update of kinds..

    I just ran the BT4 (BackTrack 4) livecd on my laptop, and i use wicd to connect the wireless adapter to my AP. Everything connects, and i can surf the net ++.. However, the problem is identical there as it was in windows 7!

    This was not the case using the slightly older Ubuntu livecd..

    I am.. totally at a loss other than ofc it might be the wireless ap fubaring something.. but why would the same thing work with identical hardware in a older Ubuntu livecd?

    I am going to run a linux rev. in a VMware session using a USB wifi adapter and see if that can stay connected on the same AP.

    Sounds like more A/V wierdness to me. Once you toss an A/V software into the mix all bets are off. The fact that you had problems with Homegroups also points to an A/V problem. Uninstall your A/V and try again. If all the machines are Win7 I would definately go with Homegroups as it works absolutely perfectly for me. :)

    Anti Virus. You should always get your network up and running with sharing tested before you install any type of Anti Virus.
