Network Connection Drop & 'Self Assigned ip' Problem...Please Help :(

[ben10]

This is a strange problem because it seems to affect so many users. Built in ethernet, PCI cards, wireless built-in, wireless cards, it just happens, and the only fix seems to be to reboot.

 

I had this problem with every installation I have tried from Kalyway 10.5.2 to my current XxX 10.5.6 installation. I am using a PCI card.

 

I am not saying the problem is fixed (everytime I say that I get a connection drop shortly after), but I seem to have changed something at least. Since I installed MacTuneUp and automatically optimized the connection for a Modem/ISDN instead of cable (which is what I have) I have not had a single drop.

 

What this seems to do is throttle the TCP/UPD send/recieve space and cut the maximum buffer down by a lot. I havent noticed any slowdowns in my download speed, but I have noticed I have not gotten any drops.

 

I previously tried messing with the MTU rate (along with every other ethernet setting) and messed with a bunch of router settings as well, to no avail. This automatic optimization by MacTuneUp seems to at least have done SOMETHING, as I havent gotten a drop, and even if I do sometime in teh future the machine has already been running for longer than it ever has without a drop. SO its better, if not totally fixed (time will tell on that one, Ill check back in a couple weeks)

I am also experiencing this problem with dropped network connectivity. I have tried:

 

* RTL8139

* RTL8169

 

Both of these cards fail for me after some "heavy" network usage.

 

I have tried three different drivers with my RTL8169. I saw no difference between the Apple and the official driver from Realtek.

 

I saw a difference when I tried out pystar's 1.8.1 RTL1000 driver... I found that the connection consistently drops out after just a small bit of traffic.

 

Also I have noticed the problem is "less" prevalent when using the 9.5.0 VooDoo kernel (on my XxX 10.5.6).. I have a Nvidia 680i if that is of any interest..

 

For now I have a USB 100MB/Sec adapter that I am going to stress test over night.

 

By the way a great utility to use in your testing is called "iperf"

 

runs on windows, linux and mac os x.. basically you setup a iperf server on another computer and then connect to it from your mac. you can really stress the hell out of your network connection... jperf is a good front end (google this stuff to find it)

I have the same problem with different network cards.

 

* RLT8139

* 3Com

* Onboard NVidia

 

I think it had to be something related to my motherboard.

 

Anyway there is no fix right?. Also we don't know what is causing those drops.

I have the same problem. After a while, my Ethernet will simply die and fever to a self assigned IP, even when not downloading massive files. I'm running on a P5NSLI nforce4 Marvell Yukon 88E8001 with skge.kext v0.2d.

 

What Ive done to re-enable Ethernet after a drop is create a finder plugin that pings google, then based on the result will reload skge.kext. This re-enables Ethernet most of the time, but I absolutely hate that I can almost never finish a download.

 

I'm on iatkos v1r3 10.5.1.

 

I think this is one of the most prevalent issues that NEEDS to be fixed...

I'm also running on a P5NSLI. There must be something with this mobo and hackintosh. I'm using leopard retail / Vanilla kernel.

I had an Asus P5N-E SLI MoBo with the same issue. The onboard LAN didn't work at all, and even after getting a supported realtek card, the etheret would cut out after 400-500 MB of downloads. I gave up on the whole project for a few months and just recently decided to pick it up again now that I need to use iMovie '09 for school purposes. My solution to the problem was a new MoBo. I got a Gigabyte P35-DS3R and have both the on board LAN and the realtek card working. After the switch I have a perfect hackintosh with full capabilities.

 

I guess the P5N just has issues with ethernet. Maybe try and get one of the Apple usb ethernet adapters. I wish I had known that before I splurged and got the new MoBo lol.

[parm289]

For the p5nsli, maybe the problem is related to the BIOS?

 

Has anyone with this card changed settings or reflash the bios and solve the Ethernet issues?

 

EDIT: And, maybe a way to resolve the drops, if everything else fails, is to assign a bandwidth throttle:

sudo ipfw pipe 1 config bw 400KByte/s
sudo ipfw add 1 pipe 1 src-port 80
sudo ipfw add 1 pipe 1 src-port 22

This would assign a maximum download speed of 400kB/s to ports 80 (http) and 22 (sftp). You can change these numbers to any ports you have open (i.e. bittorrent, ftp, etc).

 

And to delete the throttle,

sudo ipfw delete 1

 

I'm trying this now...but I would like a way to use full network speed and no have to worry about drops...

 

 

EDIT2: A cap of 400KB/s seems like a good number. I'm running a download of a 500mb file, transfer of 4.6GB worth of music from my ipod touch (sftp), normal web browsing, and im and no crash so far. The 500mb download runs at around 200KB/sec, and the stfp transfer is running at around 100KB/s. So far, no crashes.

 

 

EDIT3: Well, had my first network drop with the cap enabled. Re-loaded skge.kext and now working with a cap of 300KB/s. Gonna stress-test this and report back.

[drewjacks0n]

Just checking back in. I noticed that you guys have a P5N-E SLI, that appears to have the Nvidia 650i chipset. I have a Dell XPS 720 which has the 680i (i think?) chipset. I think its chipset related possibly?

 

Anyways, I gave up on the PCI ethernet route and went with a 7 dollar USB adapter from Fry's. OS X recognized this adapter out of the box and I have not had a single network problem since installing it. It's speed is 100MB, so while not ideal, it does at least work.

You're kidding me. A USB nic solves this issue? I'm off to Frys.

 

BTW, I'm assuming this is card TRENDnet TU-ET100C 10/100Mbps USB to Ethernet Adapter

 

Thanks,

hmm, i've made a search in the LAN & Wireless-board for "buffer"

 

and there seems to be a connection between multicore cpus (as there are no dropouts with the bootflag cpus=1) and the dropouts

somebody also mentions a problem with the tcp setting "disable flow control"

 

The origin of the problem seems to be a tcp buffer issue. The TCP settings can be viewed with

ifconfig
netstat -m
netstat -s
nfsstat -s
sysctl net
sysctl kern.ipc

The adapter that I was using was actually manufactured by a company called "Airlink". I checked the frys.com website and did not see the product. But try that TrendNET, I think the hardware that comprises these adapters is common and used throughout the industry. I'm confident it will work on your Hackintosh.

 

So with that being said, I actually went out and got a differnet motherboard. I purchased the Gigabyte GA-EP45-UD3P motherboard. I have been VERY happy with this board thus far and have noticed better boot times and over all improved performance in my Hackintosh.

 

Most interesting is that I dropped in my Netgear GA311 card (rtl8169) and it works with NO problems! I haven't had a drop yet, however I must say, I have not yet done a real true stress test. I plan on testing it further this weekend. Currently I'm testing the ability for my new motherboard to overclock my E6850 chip. Right now I have it bumped up from 3.0ghz to 3.6ghz with no problems in stability. Very cool.

 

Anyways, in short I ditched my XPS 720/680i board and got a new one, so hopefully this thread is over for me. If i notice any network drop outs with my new setup, I'll be back!

I've also read that its a buffer issue. What I understand is that the operating system is not able to flush the buffer (i guess that would be the TCP buffer, according to your post). I don't know if this is a problem with the operating system itself, or rather with the software kernel extensions (drivers).

 

I'm going to try running with cpus=1 and see if I get any drops. I guess in the short term, this may be a solution.

BTW the Trend Net USB eth didn't do the job. I fiddled with it and a couple kexts (the one from sustainable and the apple generic) to the point my 10.5.6 install got so unstable I had to revert to 10.5.5 load. Darn me for not backing it up first. I tried to get this USB nic to work on 10.5.5 and it would work sometime and then not. It also conflicted with my Logitech wireless wave/mouse by not letting it load- royal pain. Today I stopped by best buy and they had an Apple USB to Eth open box for $24.95 and it's working out very well. First Apple computer part I've purchased since my APPLE ][ (not counting ipods).

 

I'm returning the Trend Net...

[parm289]

well, tried cpus=1 and got a lot of kernel panics while using the computer. The panics were at various points and were caused by random apps. So, although I had no drops, the kernel panics, which are much more devastating, are to common to overlook.

 

I guess the best solution for right now is to avoid using

Onboard ethernet. What i've done, since the only USB wifi adapters I have are WUSB54Gv2, is tether my iPod touch to my hackintosh via USB and use it as a wifi adapter. Not very convenient, but I don't have the money to go out A

and buy a $30 USB->Ethernet adapter right now...

[382jsl881]

@parm289: have you tried the 0.2e driver from http://www.insanelymac.com/forum/index.php?showtopic=15700

[parm289]

Yup, doesn't change antything. Thanks for the suggestion though.

[danielns]

@parm289: cpus=1 solved my problem, but i can't even watch 720p videos. How can i use my ipod touch as a wifi adapter?

[parm289]

Before you start, keep in mind that this can really heat up your iPod touch, so don't be streaming episode after episode of high def video using this method.

 

1. Download and install iPhone Tunnel Suite for mac and Proxifier

2. Plug in your iPod touch via USB

3. Make sure openssh is installed and enabled on your iPod. (install through cydia and enable thru sbsettings/bossprefs)

3a. Make sure your iPod's autolock is set to never

4. Open iPhone tunnel suite.

5. Click the arrow icon in the menubar and go to preferences

6. Make sure the proxy port is 9999 (first text box in the small window)

7. Click the arrow icon again and click the option to turn tunneling on

8. Click the arrow icon again and go to the pop-out menu choice (forget the name off the top of my head) and choose "thethering"

9. A terminal window should appear. Type alpine when prompted for the password.

10. DO NOT CLOSE THIS TERMINAL WINDOW OR QUIT TERMINAL!

11. Open Proxifier and go to the proxy config screen (get there from somewhere in the menubar, I forget but you should be able to find it)

12. Enter this for the SOCKS v5 address/info:

Address: 127.0.0.1

Port: 9999

And make sure it's in the SOCKS v5 section and click ok.

13. Set whatever Internet apps you use to "Automatically detect proxy settings" through their preference menus.

 

You're good to go. Sorry that I didn't remember every detail, but i'm typing this from my iPod touch so I couldn't retrace the steps.

 

And sorry for the double post, but I remember reading somewhere that changing the network optimization with this tool:

http://www.macupdate.com/info.php/id/21115

or Cocktail would help the network problems. I'm a little afraid to try it in case it bombs my so previously brittle osx86 install. But if anyone having this problem wants to be the guinea pig, please report back with the results.

 

I think the best optimization to choose is dialup or DSL if my memory serves me correctly.

[danielns]

Thanks for the help. The iPod touch is working fine, i'm looking for a compatible wifi adapter. I also tried PimpMyOSX and Cocktail, both didn't work.

[parm289]

Thanks for the reply. Glad I could help you get your iPod working.

 

If you're looking for a compatible USB solution, just pick up the Apple USB Ethernet adapter. It's been confirmed to work OTB.

Hello all,

I'm a newbie to Mac; although not xp. In the last 8 weeks I've toiled with Kalyway, Iatkos and Idenib.; Ive formatted harddrives numerus time because I've tried to get the perfect unpanicking system. My last problem was ethernet disconnection. I use a dual core 2 intel 2.67 chip. I scoured the internet for this problem. Because of internet diasconnections I had to re-boot to get the ip back many times. Iatkos 10.5.6 has a fix = -cpus=1 ; that caused a slow down, 1 cpu is not as fast as a duo 2. After many thoughts I went into the bios. CPU SPREAD SPECTRUM was enabled, so I disabled it. I now have no problems with ethernet.

My advice is go to best buy and purchase an official Apple USB/Ethernet adapter and use that. I wasted too much time trying to get my on board nic + a few other nic cards working. I had the same issue as you. The Apple usb nic works very well with no disconnects in over a week with heavy downloading. If you buy this pm me and I'll tell you what kext to install, etc.

I currently have no problems and I'm running apples combo 10.5.6 with stock kernel 9.6. I'll keep you in mind, just in case.

Hey here is an update on how I solved this problem with my netgear NIC that uses realtek 1369. I used to get random system freezes as well as a dropped network connection. I started to notice that whenever I had heavy network traffic my network would die, and whenever I had a lot of hard drive activity, the system would freeze.

 

I thought it was the NForceATA driver, or maybe NTFS-3g that I am using to access my NTFS drives.

 

In the end, as I posted in Verdants wonderful 7-series MOBO thread, it was some funky disagreement between my motherboards "Vanderpool Technology" setting in the BIOS and the NTFS-3g driver. if I disabled NTFS-3g, I would usually not freeze, but I would still get network drops.

 

SO I disabled Vanderpool Technologies in BIOS (its some virtualization thing), and presto! everything works. I have been online and heavily using the system for the past few days without a single network drop or system hang. I feel like I am using a real Mac ! finally

 

Well, maybe this will help some people.

 

EDIT: As always, things were not as they seemed. Hehe, I am getting a little tired of this EVGA 780i mobo, might have to trade 'er in. Although my network has remained rock-solid, which is a first, the frakking system continues to suffer from random freezes/hangs. No KP, and I havent found any info in the logs. Just...freeze. I have tried patched DSDT, non-patched, and all other sorts of stuff. Well, back to the drawing board.

net drops here on Asus P5N-D SLI with RTL8139 It is network card unrelated issue coz I tested it with some 3Com PCI NIC and onboad nforce (wchich gabe me also KP) with same reluts of no connection. I used 3Com on my Asus P5Q Deluxe (broken from cheap feel3 atx...) and everything worked like a charm. My brother have Gigabyte EP35-DS3R and also don't have any drops.

 

So here I am with my network dropping and tried disabling HPET and deleting AppleHPET.kext - din't worked, just made drops less frequent. Network can go all night long torrenting but eventually it drops, and it can drop after almost no time from booting, so there is no rule when it drops...

 

Now I use duplicate nic setting method and MTU1000, and manual DNSes with everything regarding HPET enabled and it didn't drop by now (~1h), and without it it dropped quite fast. I'm testing by using torrent, opening sites and transfering to/from my XBox using FTP.

 

Will post if it drops

 

ps. forgot to add that I use iPC 10.5.6 with Vanilla kernel. Now I just uppded to 10.5.7. Earlier it didn't change much in network dropping case.
