Router: Linksys WRT54GL
Main PC wired
I am trying to transfer some blu-ray rips from the Main PC (wired) to the HTPC (wireless), but after 20-30 minutes it give me this error message and it can no longer locate the HTPC. i made sure the HTPC didn't so to "sleep" mode..
Something wrong with my home network or is it time to get a new router/adapter? everything else seems to work fine, except trying to transfer these huge files (10GB-20GB).
trying opening up ping and doing ping -t htpc see if a connection issue occurring during the transfer?
And if that is the case (I think Kewlx25 is on to something here), check for newer firmware for WRT54GL. I remember my old WRT54G router having similar problems when I first got it. Copying large files over both the wired LAN and wireless would actually result in my connection completely dropping to the router. Sometimes I could simply wait a few minutes and it would come back, but in most cases I had to actually reboot the unit.
650MB/s isn't even possible on today's Gigabit routers. I think there was a typo there somewhere.... Are you sure you didn't mean 650KB/s? If so, then yes that is unusually slow. If that result is over the wireless, I would check the signal level at either end of the transfer and move the systems accordingly. If it's over wired, a simple reboot of the router might solve it.
First, make sure there is nothing artificially bottlenecking the connection. Check the router to make sure it's not capping the traffic speed at 10 Mbps, and also check to make sure your network adapters are set to auto-negotiate the connection speed instead of being hard coded to a certain speed. The drivers can be adjusted via the Advanced tab in the network adapters settings page in the Windows Device Manager. While you're at it, make sure your LAN drivers on every device are completely up to date with the manufacturer (do not check Windows Update, go to the motherboard manufacturer's website, or even better the NIC device manufacturer's website).
