uberjon Posted December 11, 2011 Share Posted December 11, 2011 Hello. I'm having speed issues when trying to copy files from the Desktop to the Laptop. Copying files from the Desktop to the Laptop over Wireless G is very slow ? Avg 9.14 Mbits/sec Copying files from the Laptop to the Desktop over Wireless G is not bad - 18.8 Mbits/sec. Can anyone help me figure out if there a problem with my hardware or software? Setup - I have 2 computers, a Desktop & the other is a Laptop. Both are in the same room. Desktop is wired to the Router. Laptop connects to the router over Wifi. Router: Netgear WGR614v9. I get consistent (internet) download speeds on both the Desktop & Laptop ? 4 Mbits/sec. Desktop: XP Pro (32 Bit) Motherboard : Intel DG43NB.

I reinstalled the LAN drivers on the Desktop & the WLAN drivers on the Laptop, but it did not change anything. The router already has the latest firmware. I?m thinking of reinstalling Windows on my Desktop first. If that does not work, then the Laptop if I can't get things working properly. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 11, 2011 MVC Share Posted December 11, 2011 Laptop wireless card is in really 2 different modes here, when your pulling from the desktop wireless card is just downloading, transmit is just acks -- minor portion of the transfer. The router is doing the meat of the transmitting. When your pulling from the laptop, major portion of the data is being transmitted and it just receives the acks. So wireless card is doing more transmitting than rec. It has nothing to do with your desktop, and everything to do with how wireless works and what card and driver your using. uberjon and Muhammad Farrukh 2 Share Link to comment Share on other sites More sharing options...
uberjon Posted December 11, 2011 Author Share Posted December 11, 2011 I see. Then I am assuming that my WLAN card needs to be replaced? :pinch: I got this laptop in Jan 2008 -almost 4 years ago. Old age? FYI - Dell Wireless 1390 WLAN Mini-Card Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 11, 2011 MVC Share Posted December 11, 2011 Doesn't matter what wireless card you use, your more than likely going to see slower speeds while card is sending (transmit) vs when card is getting (receiving). Sure some cards are going to be better than others... But to be honest you normally don't "send" a lot of data from a wireless client. Not sure why your worried about it? And if you only have 4mbit internet, wireless speed is more than fast enough to cover that. What is the transmit power of your wireless card vs your router? ;) Most wireless cards drivers allow you to adjust the transmit power - that should help. BTW -- your also looking at the speeds every second vs the overall speed of the transfer, remove that -i 1 and just get the speed for the total 10 second test.. You won't see the variation that way ;) Now what is your speed? just did test from my wifes laptop C:\Windows\system32>iperf -c kim-pc -f m ------------------------------------------------------------ Client connecting to kim-pc, TCP port 5001 TCP window size: 0.01 MByte (default) ------------------------------------------------------------ [336] local 192.168.1.100 port 31303 connected with 192.168.1.201 port 5001 [ ID] Interval Transfer Bandwidth [336] 0.0-10.0 sec 16.8 MBytes 14.1 Mbits/sec Pretty much every one of your iperf flags is default other than the format in Mbits, you have no need to use them. And the -i 1 can be misleading.. Im going to lower the transmit power on my wifes card and move it farther way from the wireless AP. Ok you would have to do lots of tests, because wireless is always in flux, etc.. But quick and dirty - lowest xmit on her 6200 AGN card. C:\Windows\system32>iperf -c kim-pc -f m ------------------------------------------------------------ Client connecting to kim-pc, TCP port 5001 TCP window size: 0.01 MByte (default) ------------------------------------------------------------ [332] local 192.168.1.100 port 31312 connected with 192.168.1.201 port 5001 [ ID] Interval Transfer Bandwidth [332] 0.0-10.0 sec 15.1 MBytes 12.6 Mbits/sec now did same test with highest xmit power setting on card, from exact same location -- did not move the laptop C:\Windows\system32>iperf -c kim-pc -f m ------------------------------------------------------------ Client connecting to kim-pc, TCP port 5001 TCP window size: 0.01 MByte (default) ------------------------------------------------------------ [336] local 192.168.1.100 port 31319 connected with 192.168.1.201 port 5001 [ ID] Interval Transfer Bandwidth [336] 0.0-10.0 sec 16.0 MBytes 13.4 Mbits/sec The first test was card on med xmit and it was closer.. I moved the laptop to the far end of the kitchen for the low and high power test. Now keep in mind your tests are going to flux a lot, so you would have to do quite a few tests to get any statistically good numbers to work with.

uberjon Posted December 12, 2011 Author Share Posted December 12, 2011 Thanks Budman. A few months ago, my Desktop to Laptop copying speeds never dropped below 18 Mbits/sec. All my movies are on my Desktop. Now when I try to stream them to my Laptop, it sometimes buffers. I used to watch the exact same movies without any problems before. So I was trying to figure out how this happened. By the way, I ran the tests using jperf 2.0.2. That's where all the commands came from. I don't really know anything about iperf flags :cry: .

+BudMan MVC Posted December 12, 2011 MVC Share Posted December 12, 2011 Well I don't see your speeds from desktop to laptop doing anything but 18.. From your tests, it was only laptop to desktop which was slower.. If you streaming movies to your laptop, then your laptop is mostly rec packets, and only sending acks.. So you tests show your good if 18mbps is enough to stream what your waning to stream.. I would think SD would be ok with that, HD now might have some issues. If you want to watch a movie on your laptop -- here is what I would do. Plug it in, and copy the thing over at atleast 100mbps -- what 2 minutes. Then watch it direct off your laptop HDD, or put it on a thumbdrive and then plug that into your laptop ;) Or go N if you wanting to stream movies.

uberjon Posted December 12, 2011 Author Share Posted December 12, 2011 Actually, it was the Desktop to the Laptop that was slower - 10.9 Mbits/sec. The first one was From the Laptop to the Desktop - 18.8 Mbits/sec Looks like I'm stuck with G for now. Or I can buy a wireless N card for the Laptop. Thanks. Does anyone have a suggestion for a good WLAN N card? Intel 6300 AGN? 5300 AGN? Thanks. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 12, 2011 MVC Share Posted December 12, 2011 "Actually, it was the Desktop to the Laptop that was slower - 10.9 Mbits/sec." No that is not what you posted.. You posted desktop server was 18 Laptop as server 10 If you run iperf as server mode on desktop then laptop is downloading "rec" data and only sending acks If you run iperf as server on laptop, then laptop is sending data to desktop, and desktop only sends acks. what is the .101 box? "Client connecting to 192.168.1.101" BTW - if your going to buy a N card for your laptop, your going to need a N router/AP as well -- I show that WGR614v9 as G only.

uberjon Posted December 13, 2011 Author Share Posted December 13, 2011 You're way better than me at this, so you're probably right. The .101 box is my DSL Modem/Router, which is a N router. I disabled the wireless (G/N) on it because the box is, IMHO, a complete waste of money - poor range, drops connections at random, does not display line stats properly etc. It's a Linksys WAG120N & I still regret buying it, but that's a different story. As a modem, it's just average. OK. Just copied a file from the Laptop to the Desktop at ~14 Mbits/sec. Then I tried copying the same file back from the Desktop to the Laptop, & the speed fluctuates between 4.5 & 6.5 Mbits/sec. But those speeds used to be at ~14 Mbits/sec too.....I think But I guess nothing can be done about this without going 'N'. Thank you Budman.

+BudMan MVC Posted December 13, 2011 MVC Share Posted December 13, 2011 "The .101 box is my DSL Modem/Router" What -- that makes no sense with this from your iperf post Client connecting to 192.168.1.101, TCP port 5001 You were running iperf on your router? If you on your laptop and copy a file from a share on your desktop, that is not transmit issue with your wireless card. Its recv data, and only send acks during the transfer. Which is completely opposite to what you showed in your iperf posts?? But your right you should be able to pull more than 6.5Mbit/sec over wireless G -- even 14 is on the low side.. A good wireless g should be around 18 to 20Mbits, screaming is like 20 to 23.. 23 is just freaking SCREAMING, planets all aligned, etc. So question for you -- your wgr614 is being used just an accesspoint -- how do you have it connected.. You could be doing a nat between your devices which could be causing you all kinds of issues. Please draw out how your wgr614 is actually connected to your dslmodemrouter Could you draw out your network and how everything is connected. And if possible distance from wireless router/AP that your laptop is at, etc. Link to comment Share on other sites More sharing options...
uberjon Posted December 13, 2011 Author Share Posted December 13, 2011 Sorry I typed it wrong. :argh: . I meant to say that .100 is my modem/router address. I know it does not make any sense now. Let me see if I can draw my network. .101? No idea. EDIT: .101 was *probably* my Laptop??? I do not know. DHCP is turned off on my Netgear router. So it's just acting as an access point now, right? Linksys is bang next to the Netgear router. Distance from Netgear router to Laptop is typically less than 10 feet.

+BudMan MVC Posted December 13, 2011 MVC Share Posted December 13, 2011 .100 really -- that seems to be an odd number for a gateway address. Normally you see then on low end .1 or high end .254, etc. .100 is normally the first IP given out in dhcp scopes for most soho routers.. From output your lap is .101 Host Name . . . . . . . . . . . . : LAP Description . . . . . . . . . . . : Dell Wireless 1390 WLAN Mini-Card IP Address. . . . . . . . . . . . : 192.168.1.101 and .100 is your desktop Host Name . . . . . . . . . . . . : desktop Description . . . . . . . . . . . : Intel? 82567V-2 Gigabit Network Connection IP Address. . . . . . . . . . . . : 192.168.1.100 And both of those devices show your dhcp server and gateway as .1 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 in your iperf outputs you clearly show your lap connecting to your desk and doing 18 [1792] local 192.168.1.100 port 5001 connected with 192.168.1.101 port 1254 [ ID] Interval Transfer Bandwidth [1792] 0.0-10.0 sec 22.4 MBytes 18.8 Mbits/sec See in that desk is server .100 and lap is client .101 and .101 is connecting to port 5001 from port 1254 And then in other post [1832] local 192.168.1.100 port 1355 connected with 192.168.1.101 port 5001 [ ID] Interval Transfer Bandwidth [1832] 0.0-10.1 sec 13.0 MBytes 10.9 Mbits/sec See connecting to .101 on port 5001, from client port 1355 Port 5001 is the default port iperf server runs on. Even shows Client connecting to 192.168.1.101, TCP port 5001 .101 being laptop from your ipconfig post -- so that is desktop connecting to laptop where you had slow iperf, when lap connected to desktop you showed normal wireless g speeds of 18.8 which what I would call normal/good wireless speeds for G.

uberjon Posted December 13, 2011 Author Share Posted December 13, 2011 I hope my edited post made some sense. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 13, 2011 MVC Share Posted December 13, 2011 yup from that drawing your good, only using lan ports only on wgr614, and its dhcp server off - then its an accesspoint. Yup that is exactly how it should be setup if you don't want to use wireless of your wag120. So why are you not using its wireless again? What wireless are you running? Open, WEP, WPA, WPA2 --- you using tkip or aes on your wpa/wpa2 settings? Link to comment Share on other sites More sharing options...
uberjon Posted December 13, 2011 Author Share Posted December 13, 2011 I'm using WPA2-PSK [AES]. The main reasons why I do not use the wireless of the Linksys are because it has poor range & drops connections at random. I go 2 rooms over & I get almost no signal. That's why I'm still using the Netgear. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 13, 2011 MVC Share Posted December 13, 2011 How did you have your wag120 setup, if you do not have N then set it to G only - this may increase your range and stability. Also what driver are you using on your wireless card? go into the card config and what is the actual Hardware ID string, and we can see if we can find you a better driver than some old 4 or 5 year driver from dell you might be using? I do believe the 1390 cards are broadcom chips, maybe the bcm9431X line? What firmware you running on the 614? Link to comment Share on other sites More sharing options...
uberjon Posted December 14, 2011 Author Share Posted December 14, 2011 The WAG120N was always set to 'G-Only' (when I used it), but it did not work. :( The WLAN card driver version is 5.10.38.26, Dated 10/22/2008. According to the Dell website, I have the Latest version: A235.10.38.26 (Driver). Yes, you are right, it is from Broadcom. Regarding the series, I went to Details -> Service->BCM43XX Hardware ID string? Is this it? PCI\VEN_14E4&DEV_4311&SUBSYS_00071028&REV_01 PCI\VEN_14E4&DEV_4311&SUBSYS_00071028 PCI\VEN_14E4&DEV_4311&CC_028000 PCI\VEN_14E4&DEV_4311&CC_0280 I have been running 1.2.30 on the WGR614v9 for a while now.

uberjon Posted March 11, 2012 Author Share Posted March 11, 2012 Update: Forgot to do it sooner Formatted & reinstalled XP. Copying from the Desktop to the Laptop at 19.5 mbit/sec. :jump: Link to comment Share on other sites More sharing options...
+BudMan MVC Posted March 11, 2012 MVC Share Posted March 11, 2012 Yeah -- and your point is? Last time you saw MBytes 19.4 Mbits/sec So how is that any different? Do we have to go over how the router xmits faster than your card all over again? Run Iperf -s on your desktop and test from your laptop on .101 with -c to .100 Post output Now run iperf -s on you laptop and connect from desktop with -c from .100 to .101 post output.

uberjon Posted March 11, 2012 Author Share Posted March 11, 2012 The last time, Desktop to Laptop: ~9 mbit/sec (& sometimes even slower). It fluctuated a lot. Now, its closer to 20 mbit/sec. NetPerSec shows a nice, almost flat line. Copying files to & from the Laptop are more or less the same speed now, which is what I wanted. Anyway, thank you for your help, Budman. By the way, do you use Visio to draw your network diagrams? If yes, which version? It's really neat! Link to comment Share on other sites More sharing options...

+BudMan MVC Posted March 11, 2012 MVC Share Posted March 11, 2012 Again that is not what I saw from your postings ;) And we went over why that could be. You could move your laptop somewhere else in the house and have the same issue.. I showed you how transmit from a wireless card can be different depending on its power setting and location. The wireless protocols allow for many different xmit rates.. Depending on the signal, depending on the noise, depending on the power setting it can fluctuate. Just because laptop says its connected at 54mbit does not mean it is transmitting at that rate, etc. Glad your happy with your current connection speeds, but does not mean your reinstall had anything to do with it. And does not mean that next time you test it going to show the same thing, etc. and yes I use visio - current version on this box is 2007 Link to comment Share on other sites More sharing options...
uberjon Posted March 12, 2012 Author Share Posted March 12, 2012 Why not just buy a USB drive? I stream HD movies to my laptop. And having a strong, stable wireless connection definitely helps. :) Link to comment Share on other sites More sharing options...
