Routing Problem ??

    I have a WRT54GS V2.2 with HyperWRT 2.0 and I want to use it as an access point on my existing network.
    The Problem is: Internet over the WRT54GS works fine (even with large downloads), but access on other network shares fails (Neither wireless nor connected to a lan port works). I can view the files on a network share, but if I open a file (e.g. JPG with abaout 200KB). The connection drops and the viewer application crashes.
    Could this be a routing problem?

    Here is my network configuration: (all on the same subnet 192.168.10.XXX)
    [Internet] --- [existing linux router(.10)] --- [switch] --- [WRTG54GS(.2)] --- [host1(.200)]
    / \
    [Host2(.20)] [Host3(.30)]
    On the existing Linux router DHCP is enabled. Additionally it is configured as a DNS.

    The configuration is:
    Static IP:
    Subnet Mask:
    DNS 1:
    Router name: WRT54GS
    Host name: WRT54GS
    Local IP:
    Subnet Mask:
    DHCP: disabled

    Advanced Routing:
    Operating Mode: Router
    RIP: Both

    Routing table shows:
    Destination IP Subnet Mask Gateway Interface LAN & Wireless WAN (internet) WAN (internet)

    I can ping all hosts from the wrt54gs. And all hosts can ping the wrt54gs.

    Any ideas?

    Thank you.

    doesn't sound anything like a routing problem, it sounds like your having a "High Throughput causes disconnect" congrats

    "High Throughput" ?
    If I try to open a 200KB JPEG Picture from a LAN Network Share using one single wireless connection without any other traffic on the whole network?
    I don't think so.

    Streaming large files from Internet over WLAN works great. Only LAN doesn't.

    Any other ideas?

    that thread is a mixture of people having simialar issues with the same symptoms, so you may be best looking there, it usually happenbs when sending files from lan to wlan and usually causes the router to reboot... have you noticed the router restarting?

    The router doesn't reboot, it just stalls!
    It happens on any kind of connection LAN->LAN, LAN->Wireless, Wireless->LAN.

    I allready tried many different types:
    Always the same. I can view a directory listing on the share, but cannot do something with the files.
    It was the same problem with the default linksys firmware, too.

    I found out that, if I try to copy a 100KB JPG file from the network share to local hdd, it stalls for about a minute (no traffic) and then copies the file correctly. During the minute the Explorer Window freezes.

    I found out that the connection drop seems to create an error on the network share:
    If this happens on my Samba File server the smbd.log shows up:

    oplock_break: receive_smb timed out after 30 seconds.
    oplock_break failed for file Backup/Data/Media/LOGOFF.WAV (dev = 903, inode = 15188012, file_id = 21).
