No promises here but I ran into problems with large files (.avi and .iso, over 500mb). The network would disconnect or the
transfer would mysteriously stall half way through.
There is a registry fix you might try...
Start -> Run -> Regedit
Path in to :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters
Set the "Size" parameter in the right pane to 3.
If it's not there create it as a DWORD value and set it to 3.
This solved the problem for me... I hope it works for you.
Hmmm... There might be driver issues or any number of other bits of strangeness because of the differences between "update install" and "clean install"... but there could be other reasons as well...
I think the first thing I'd do is get everything hooked up on known-good network cables. No wireless.
If things suddenly start working as they should you are one step closer to a solution... it's probably the wireless.
If they don't get better, at least you've got a spare network cable or 2 floating around.
Excellent... Process of elimination...
Let me know how it goes...
Actually, an afterhought (I'm bad for this)... If things don't get better, you will know you still have the problem connected to your network which is also good information.
Ahhh, I see... so you're on wireless internet and wireless networking... Makes me think about that "interference" problem I speculated on.
I think it's clear you have a WiFi connectivity issue... so lets see what we can do about that....
Is there anyone you can impose upon for a temporary connection to their wireless from your laptop?
Ideally you would want a situation where you could bounce a few gigs of files back and forth between your machine and theirs, multiple times, for testing... If that goes well then we suspect your router...
A couple of things to check in the mean time...
In the router setup ... is there a "CTS" or "Flow Control" option on the wireless setup? This should be on.
In your laptop ... in the adaptor settings "Flow Control" should be enabled for both RX and TX.
In your security settings on both ends you should be in WPA with AES encryption whenever possible.
(In my experience this is the most reliable setup)
And one last point... I noticed you have your router very close to your receiver...
It may help you to move it over into one of the doors on either side, as far from the receiver as possible.
But the real test will be to connect to someone else's lan and see if the reliability problems move with you.
Ok... to be fair... I'm not going to read your router manual and go through it page by page on a BBS... So please consider this a one-time event (Thanks).
That said, no I don't think there's anything on that page you need to worry about.
You may want to enable "Wireless Isolation" and "WMM" from the next page, however.
A couple of suggestions...
Your network name (SSID) and pass phrase (PSK) shold be as complex as you can bear. Do tricky stuff like using big words backwards... the harder it is to guess the less chance of someone interfering or breaking in. Avoid network names that invite curiosity... eg. "Private Network" is an open invitation to hackers... (Don't underestimate a neighbor's determination at trying to get free intenet access, especially near the end of the month when they've used up the quotas on their own.)
You should try turning down your beacon power. Find the lowest level you can comfortably use in your home. (Mine's at 25% on a D-Link router) This limits the number of people who can "see" your router.
I see your router supports "Hidden Wireless"... (page 28) and you should select "Invisible" mode. This reverses the handshaking so that unless you know the router is there, you won't see it on the networks list. This will require some changes in your Win7 wireless setup... I believe the checkbox is "Connect even if this node is not broadcasting" (or similar).
You should also enable Auto channel scan. This will allow the router and computer to automatically pick a channel with no other signals present which will greatly reduce interference from other routers in your area.
Aside from that, it's all about testing....
Let me know how you make out on a different router....
Yes this could be a security or interference issue... It's hard to tell which.
People actually do drive around looking for wireless signals to probe. When they find an unsecured one, well, all kinds of stuff goes on.
Check this out... How to build a tin can waveguide antenna Some guys are saying they get better than a mile range out of it.
One of the latest tricks on wholly unsecured systems (No passwords, group shares, etc.) is called "Planting"... Essentially what they do is create hidden folders on your system, install a mini-ftp server, fill them up with porn or other illegal stuff, then tell all their friends where to find it. You end up running a server... one that's about to land you in jail.
My wirless "crashes" from time to time. I live near an apartment building where it seems every other tenant has a wireless setup (40 at last count) and every so often we get collisions. Somebody sets theirs on the channel I'm using (because they can't see my router) and down it goes... Of course their's goes for a crap too, they can't figure out why, and they do a reset, letting me get back to business.
Interference wise, all kinds of stuff can mess up a wireless signal... My son gave us a microwave that ended up in storage because every time we turned it on the wireless would shut down. Ham radio operators, CBers, TV/Radio broadcasters... passing cop cars... anything generating an RF signal can do it... Including your dishnet receiver!
Anyhow... let me know how your testing goes.... Then we'll decide what to try next.
