HeyIm having stability problems while streaming and moving files wirelesslybetween two PCs, one with Windows 7 RC build 7100 and one with Windows XP. Streaming material between the two is generally slow and frequently fails since the connection seems to come and go when it wants to. The pc running XP uses a 802.11g wlan connection and is linked to the other computer, which uses 802.11n, via a Netgear WNR3500 N-router. I know that the max. theoretical speed is 54mbps since theres a 802.11g-device involved, but shouldnt I at least be able to get a stable connection?When it works, I get transfer speeds of about 600-650KB/s. When I do similar things on two PCs running XP (802.11g on both) I get significantly better stability and performance. What can I do to get normal speed and stability on the PC running Windows 7? Reinstall XP? :)Are there any applications that I can use?Im sorry if I overlooked something simple or anything like that - network and file sharing is not really my thing.

Hi, Thank you for your post. As we know: 802.11N 108M 802.11G 54M The transfer speed depends on the lower speed card (802.11G on the Windows XP computer). Meanwhile, since the connection is wireless, the speed is also related to the signal strength; please check if the speed will increase after moving both computers closer to the router. Additionally, please also ensure that the drivers for the wireless NICs on both computers and firmware of the router are all up-to-date. Hope this helps. Thanks.Nicholas Li - MSFT

Thanks for your answer. Although both computers have 54M as their theoretical maximum speed, shouldn't I be able to transfer filesfast enough tostream amovie (not HD) thats saved on the other PC?Right now that seldom works.Signal strength is not a problem. What I essentially wonder is if there's any trick that I can use to make file sharing quicker when using Windows 7. The drivers and firmware are the latest released by the different manufacturers.

Put a N adapter on the XP comp. I use a G adapter on my comp and it BARELY handles YouTube without pausing to buffer, and can't handle it if I have multiple videos going, or a download in the background, so G is bad for streaming videos, unless if you want the video to stop every few seconds and buffer the video!Hello!

OK to stream a 720p video you need less than 2 meg connection so speed should not come into play here.What does come into play is N the standards for N where just released so any older N products may or may not be up to the standards.I have found N to cause more issues than it is worth, if your rpouter allows it turn N off.Now on the Wi-Fi, the signal strength has nothing to do with bandwidth throughput (usable bandwidth).You need to look at your wi-fi setup and those around you (Wardrive) use the clearest channel and see if thingsget better.I use a B mesh network locked down at 2 meg as it is more stable, to connect 4 homes / offices together, I watch netflix / huluI watched Lost on ABC.com in HD with the throttling off without any buffering issues.

Thanks! Thats the kind of answer I want! :)I will try turning the N-system off and use the G instead. I know signal strength doesnt affect the bandwidth, but someone asked so I answered. =)I might try B too, although it feels a bit.. old. Again, thanks!

B? That is weird, I thought N was supposed to give more bandwidth and better speed, not make you revert to B! Maybe you should try your N setup again.- forum9851 :)

Well, so did I. I will try this and see if it solves any problems...Locking the router at 54M might give better stability and better compability with older laptops taht use G... I'll look around.

I have also experiencedvery slow speeds on between windows 7 any windows XP or windows 2003. Regarding video playback, over WiFi to a WIndows 2003 system playback of XVid AVI 320x240 video plays smoothly, however, DVD quality MPEG (2.5-6MB bit rates) just isn't usable with constant pauses and spurts. I was initally copying 5 GB of files via XCopy from an XP system which uses atheros for the wifi adaptor on an XP Prosystem. The XCopy was issued from the windows 7 system (also uses atheros) via a mapped driveto the XP system. This copy took over 4 hours over 802.11g. To eliminate the WiFi signal strength and WiFi saturationI also tested a wired connection.I connected the two systems directly to each other via a crossover cable and disabled the wireless connection on both systems. The XP system showed 100MB (marvel yukon)connection speed, the win7 system (also atheros)just showed connected (dropping the display of the connected speed removes useful information). I then proceeded to copy another 5 GB of data from the Win7 system to the XP system, this took over 2 hours. On an XP to XP copy this copy would be complete in under 20 minutes. Windows 7 appears to have issues with network speeds in general, not just WiFi.

Sweet! Somebody's having the same kind of problem as I have! I agree with you - Windows 7 needs some work in the network speed area.

I Have been running a Windows home server for a couple years now to stream media through the house, back ups and storage of all my digital mediawith no major issues.With windows 7 I get slow network speeds aswell to the point i am unable to stream an mp3. Other days its lightening fast, just this morningit sustaineddata transfer at 78 meg/sec for entire 7 gig. As there seems to be no common circumstanceswhen the slow downs happen i can't point to why, Even reboots of the entire network (router included) deosn't seem to make a differance. Also im having issues accessing the server from windows 7,loosing permissions constantly,explorer hangingwhen browsing tthe network, downloads from the net failing, pages not loading fully. It all seems to happen while i can't copy at full speed across the network. All thse things happen at once and it seems to be pot luck when it does happen sometimes its half waythrough streaming a movie other times its while im web browsing, even when im out in the gararage streaming mp3s it happens.The server and win7 boxes are wired and 2/3 laptops are wireless.

Dave, thats exactly the kind of problems I'm experiencing too.Sometimes it works accetably, but usually I have the same issues as you do, including that windows explorer hangs and transfers that fail.I guess I'm going to install XP again then. I haven't tried the previous tips about locking the network in G yet though. I'm kind of sure that won't help at all.

additional issue (variation):browse remote folder on an XP system with about 12,000 HTM files, sort date descending.It takes upwards of a minute on a sold full strength wifi connection (802.11g: 54Mbps)to load the directory contents.Select the first 30-40 files, about2MB max. Browse back to a local folder and select paste. The copy dialog box says computing for several minutes and never actually copies and eventually bogs down the file explorer. The only way I have found to copy from folders with high file counts is to use XCOPY and either a file name or date copy filter. Copies from folders with only a few hundred files go right through as expected. The same operation succeds between two XP or XP to Win2003 systems. I can't decide if this is a network issue and the file count is too high to be efficient over a LAN or if it is a shortcomming of file explorer.

Hi Samantha, The first thing I would try, and I know it may be a pain because of the setup you have, but if you can plug both computers into a hardwire connection it will really help in troubleshooting. If the problem goes away then try one computer wireless and the other wired, then switch. If the problem does not go away then try copying a large file (500MB at least) from one computer to the other, divide the size of the file by the time it took to transfer and you will have the speed of your sustained in MB/s second, divide by 8 to get the Mb/s (wireless speeds are measured in Mb/s as well as most other network hardware). You should not have any problems streaming large video files across your network as it does not take much bandwidth. It could also be an issue with the software you are using to stream the media, I was using VLC media player for HD video files but it had issues on all my computers (both mac and pc) streaming the files I am using - probably more due to the type of media file and the software combination than anything else, but I am giving it as an example here. What OS were you running on the Win7 pc before, if any? Did it have any issues then? Also if there is a way you can bring a third pc into the mix to test streaming movies and copying files you can help isolate the issue but it isn't a requirement. I would also check some of what Bubbapcguy said, if you haven't already. If you have neighbors with wireless they could be on the same channel as you, so you may want to try changing the wireless channel on your router. The default on most wireless AP's is channel 6 and there are 3 non-overlapping channels - 1, 6 and 11, so try changing it to one or eleven. I would also disable wireless N on your wireless, just use G as N is not that much faster (if its faster at all) in reality. I have not heard of anyone getting better than 40Mb/s sustained transfer on N, and with G most people are able to get sustained transfer of 36Mb/s. I would not advise 'locking' your wireless bandwidth to each machine down to 2Mb/s as this will not help your issue, unless you have a lot of PC's besides the two you mentioned connecting to your wireless at your house (like 5 or more at a time). I hope this helps some! Greg

I am using a Motorola WA840G WiFi AP and it supports 802.11 A/B/G only. It is plugged into a Netgear DS116 10/100 hub, the same hub that both of my Win2003 servers are hooked into. For the Wired Win 7 & WinXP, I hooked into this same hub. I am on WiFi channel 5 and my neighbors are on other channels with only Fair signal quality. The Win7 system originaly had WinXP home (it is a brand new Sony W netbook). I ran it stock for only a few hours so I could confirm all harware was functioning and then loaded Win7. The XP Pro system is a 1 year old Toshiba U405 with 3x the RAM as the netbook. THe file copied is an MPEG of size 1.30 GB (1,403,736,064 bytes) averaged 2.526MB/secwired Win2003 -> WiFi Win7averaged 10.065MB/secwired Win2003 -> Wired Win7averaged 2.132MB/secWiFi Win7 -> wired Win2003Both wired and WiFi playback of the MPEG were acceptable today (the test video is a 2.1MB DVD quality MPEG). I have updated the WiFi driver to a newer than the out-of-box Win7 Atheros driver to the latest Atheros Vista driver from www.atheros.cz.I am using Media Player or PowerDVD to play over a mapped drive. another useage test:I selected 60 files, about 2.2MB out of 19,000 HTM files on the Win2003 wired server and accessed from the WiFi Win7.When paste was initated on the Win7 system the target folder had only 5 small files already in residence.It remained in Preparing to Copy mode and "Calculating" mode for 3 minutes, then copied the files at 324Kb/sec. Repeated the test but with the target folder having 4,700 files in the target location.It remained in Preparing to Copy mode and "Calculating" mode for 3 minutes, then copied the files at 124Kb/sec. ============= XP comparisions averaged 1.611MB/secwired Win2003 -> WiFi WinXPaveraged 7.829MB/secwired Win2003 -> Wired WinXPaveraged 2.316MB/secWiFi WinXP -> wired Win2003I selected 60 files (the same files the Win7 system copied), about 2.2MB out of 19,000 HTM files on the Win2003 wired server and accessed from the WiFi WinXP. When paste was initated on the WinXP system with the target folder having 15,000 files in the target location.It immediately began to copy the files and took only about 20 seconds to copy the 60 files. Something I have observed: when Win7 begins to copy a large file it does appear to have better bandwith useage, however, when there are large numbers of files being copied (such as my copying about 5GB of MP3s over the network or browsing a folder with a lot of files) it has issues.I have seen the file explorer lock up and grey out periodically when browsing folders with a large variety of file types or a large number of files, locking me out for 10-20 seconds at a time and I do not experience these lags on XP.

Superswede,Have you tried disabling Jumbo Frames in the network adapter properties on both machines? You don't need it enabled unless you have a specific need for the configuration. Also, try disabling/uncheck the "Let windows turn off power" in the power settings of the network adapter.A couple of easy changes to try before reverting back to XP.Some other thoughts on the inconsistency: Is your anti-virus/security software scanning the files being transferred/streamed? Do you have a Win 7 compatible version on the Win 7 machine? Vista versions cause problems.ASUS P4PE-P4 Extreme 3.4gHz-2gb G.Skill PC3200-XPSP3:55gb-Win7RC:17gb-DATA:500gb-ASUS N6800GT

Nano Warp,I looked around and googled Jumbo Frames for my network adapter D-link DWA-547 but I couldn't find anythign that made sense... I couldn't find a setting called "Let Windows turn off power" either. As far as I can see, my antivirus, Avast Home (latest), can't be downloaded in different versions for different OS's.

Superswede,Click the Start orb-type device manager in the search box-then select that program from the results. Expand the network adapter item-right click on the wireless adapter and select properties-you should see a power management tab-open it and uncheck let windows turn this device off-click ok- while you are there- check the advanced tab and check the drop-down list for jumbo frames enabled/disabled and select disabled.now close out and test.Are you using the Vista drivers from dLink? here.(It shows as an AU & NZ product, correct?) They will work. Something may be missing if you are using the Windows provided driver. The Avast home version specs only show compatibility up to Vista. You can get Win 7 compatibletrials here. You could disable the protection and try a file stream test before changing. The Vista versions of av software can cause problems (however subtle or major) as the Win 7 core is different than Vista.I am leaning towards the Avast causing the problem due to the fact that it's not designed for Win 7 and you are getting network connectivity.ASUS P4PE-P4 Extreme 3.4gHz-2gb G.Skill PC3200-XPSP3:55gb-Win7RC:17gb-DATA:500gb-ASUS N6800GT
