April 21, 201214 yr Author I ripped three movies, 1 bd, 2 sd for a total of 30.7 GB to transfer. I dragged the folder to my media shared folder in the unraid server, and let it transfer. I noticed the transfer speed was at 22 MB/s. I left to do some other stuff. I came back about 12 min. later, and I noticed the speed went down to 10.4 MB/S. Prior to transferring the movies, I was messing around with my WNDR3700 settings reserving the address for my devices so the IP address wouldn't change. I am using the PCI listed on my signature. Is the network transfer speed being affected due to changing my router's settings? I can live with 20 MB/s at least, but 10 MB/s come on!

April 21, 201214 yr Author Just finished ripping another movie that some how got deleted after parity check...weird! This is the 2nd time this has happened. -It is a 20.1 gb movie, started transferring @ speeds of 40 MB/s. -It slowed down to 38 MB/s after 30 seconds. -Staying @ 38 MB/s after 1 min. -Staying @ 38 MB/s after 6 min. -Completed the transfer in a little over 9 min. and transfer speed remained at 38 to 38.5 MB/s. I think I found the issues. When I re-started the router, I noticed the LED activity light for my W7 PC was yellow, which I believe is a 100 mbps connection, which explains why the transfer started at approximately 22 MB/s, and it slowed down to 10 MB/s. So pretty much my W7 was being the culprit of the transfer and not the server due to --->ME<--- changing the IP address within the routers set up screen. I've been learning a lot of networking stuff in the last 3 weeks! I'll change it to solved for now. Sorry for the false alarm!
April 21, 201214 yr Author Never mind about the issue being solve. After completing the transfer, I went to unmenu/system info/ethernet info and this is what I go.

April 22, 201214 yr Author What type of cable? It must be CAT-5e or better. Its a cat5e. I terminated it myself. May be I didnt do it correctly and thats why I'm getting those errors.
April 22, 201214 yr The cable may be the initial cause of the problem. A cable tester must be used after terminating cables.
April 22, 201214 yr Author The cable may be the initial cause of the problem. A cable tester must be used after terminating cables. Yeah, I'm getting one tomorrow.
April 22, 201214 yr What type of cable? It must be CAT-5e or better. Its a cat5e. I terminated it myself. May be I didnt do it correctly and thats why I'm getting those errors. For gigabit speeds you indeed need cat5e or cat6 cabling. I suggest you test with a prefab cable. Good cable quality (including the connectors) is of paramount importance. Bad cabling is very often the cause of poor network performance (talking here out of my profession).
April 22, 201214 yr Author Yeah, I never thought my cabling could be the culprit until I excluded all my devices. Ive got a couple other cables I can try, but they are not long enough to replace my current cable.
April 22, 201214 yr Author Well, I went to the store to buy a cable tester, and the cheapest one was like $30 dollars...So, since I am not doing any more ripping and transferring movies to my server, I decided to look elsewhere. I got all my stuff from monoprice.com, and it came out to be less than $30 dollars with all the little extra stuff I got.

April 25, 201214 yr Author Got my network cable tester and the cables are good. I don't know what else to test? And I dont know why I get those error:18 frame:9? Anyone?
April 25, 201214 yr When you say the cables are good, I take it to mean you tested them with a continuity checker, not a bandwidth capability meter, since a real tester costs $1K+. In what order do you have the wire colors? The actual colors matter a little bit, as the twist rates vary, but the pair splits matter a LOT. You should have one color pair at each end (1,2 and 7,, one color pair in the middle (4,5) and one pair split across 3 and 5. If not, you will have all sorts of problems. If you simply have the color pairs at 1&2, 3&4, 5&6, 7&8 like a telephone set, it will pick up interference and drop data like crazy.

April 26, 201214 yr Author what firmware is on your router? WNDR3700 Firmware Version: V1.0.7.98NA GUI Language Version: V1.0.0.64 I upgraded the FW a couple of weeks ago. After doing that, I've been having a hard time reserving IP addresses for my devices. All my devices do not come up on the list, and if they do they were out of order, which it didn't used to do that. I've had to add my devices manually in order the reserve an IP address. I'm wondering if the new FW has anything to do with my issues now!
April 29, 201214 yr Author I was reading someone else's post: http://lime-technology.com/forum/index.php?topic=19839.0. I ended up enabling the jumbo frames in my W7 PC by following this link: http://www.maximumpc.com/article/howtos/how_enable_jumbo_frames. I also did the jumbo frames for the unraid server MTU=9000, withing the network config file in the flash drive. I restarted the server, and proceeded to transfer a 20gb media file. I first noticed the speed was consistent and approximately 3 MB/s faster. It stayed constant at 35 MB/s to 36MB/s. The files took a little bit less than 8 min. to transfer. I went to my unmenu system info, and I did not see any errors or dropped packets in my eth0 like I used to: NIC info (from ethtool) Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: umbg Wake-on: g Current message level: 0x00000007 (7) Link detected: yes NIC driver info (from ethtool -i) driver: e1000 version: 7.3.21-k8-NAPI firmware-version: bus-info: 0000:02:06.0 Ethernet config info (from ifconfig) eth0 Link encap:Ethernet HWaddr 90:e2:ba:11:a3:ac inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RX packets:2204338 errors:0 dropped:0 overruns:0 frame:0 TX packets:929826 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2479680770 (2.3 GiB) TX bytes:97901211 (93.3 MiB) Nice....no more errors, dropped, or frame errors at all. Seems that it is working now. Thanks. This is awesome. I am using version 5RC1 unraid by the way .
