    EDIT 2: New information again, I tried copying the files without using a homegroup and it all worked just fine. Any ideas as to why things transfer fine without a homegroup and just regular sharing but not with a home group? Any help would be appreciated, I would really rather use a homegroup instead of regular file sharing.

    EDIT: New information: Still looking for help, however new information. I borrowed a friends laptop and connected it to the network (wired connection) and the same problem is happening. That means the problem is clearly on the HTPC. Any ideas what could be causing it the slowdown when transferring files from the HTPC to other PC's but leaving the HTPC able to copy files from others (incoming files to HTPC fine, outgoing files from HTPC slow).

    Any assistance would be appreciated. Original Message Below.


    Dear TechGuy Forums,

    I am having an issue I am hoping someone here can help me with. Currently I have two PC's, one running Win 7 Pro and the other Win 7 Home. The Win 7 Pro PC is my gaming PC and the Win 7 Home PC is my HTPC. They are both linked via a router (Cisco M10 Valet) and both via wired connections.

    Recently I thought it would be neat to turn my HTPC into a media/file server as well so I can access files on it from my Win 7 Pro Gaming PC. As such I simply made a homegroup linked the two and added my media library on the HTPC to the list of folders to be shared on the homegroup.

    Everything worked fine up-to that point, here is where the problem comes in. The HTPC can copy files from my Gaming PC without any issue, can copy a 500MB file in a matter of seconds. However when the Gaming PC tries to copy a file from the HTPC the transfer speed is in the area of 2-10kbps. Clearly something is wrong yet I have no way to tell what side the HomeGroup the problem is on. Currently I don't suspect it to be on the HTPC side as I did a fresh install of Win 7 and all related HTPC software (XBMC + Apps) under 2 weeks ago. As such its about as fresh as a new born baby.

    One thing that I find quite vexing is the gaming PC has zero problems with connection speed when it comes to the internet. Nice and fast, no problems. The same is true for the HTPC. Both are in the range of 35-38 Mbps Down and 4-5Mbps Up. As such its a very confusing problem. I have also ran checks on all hard drives to search for bad sectors in case it was a hard drive issue yet nothing was found. I also tried using a different router (a WRT54GL) to make sure it was not something like that, the symptoms were the same.

    I really think its a network problem, it is just outside of the realm of my expertise.

    Both PC's specs in full are below, any ideas to narrow down the problem, or things I can check would be most helpful.

    Thank you very much for your time and assistance everyone, Its most appreciated.

    One suspect is the cable connecting the HTPC to the router. Remember that four or eight wires are used, so Data could move freely in one direction but there could be trouble in the other direction.

    Wow, I did not even think of that, actually the cable connecting the router to the HTPC is slightly damaged. The pin connecting it into the router does not hold on its own, its just sort of hanging there. I am going to go and check it now, see what I find out. Will report back. Thanks for the idea, totally did not consider it.

    If you have any other ideas I would love to hear them. Now off to dig around for a replacement cable.

    Well, checked and that's not it. Replaced it with two different cables and both are the same. No difference. I also checked the original and besides the pin not holding it in place its undamaged.

    Any other ideas?

    Thanks again for your help,

    Thought of two things.

    Swap the router LAN ports used by the two PCs (just in case some nonsense is happening in the router's ethernet part).

    Try the HTPC in Safe Mode with Networking.
