Network adapter not working

Hi,
This has been quite a confusing few days with this network adapter. It's a Realtek 8139C based card, but for some reason Arch refuses to get it to work with either 8139cp or 8139too modules.
Both have been added to rc.conf modules list (independently and together) & I've tried blacklisting one then the other but eth0 still doesn't show up in ifconfig. Even with 8139cp blacklisted, at boot I still get a message about that module telling me to try 8139too instead. I also get a message saying: "PCI: Unable to reserve I/O region #1:100@de00" and that something fails with error -16.
So far, the only way I've managed to get the card working is during install and getting the setup program to probe for a driver and setup dhcp itself, which to my mind shows that the card is fine, as I managed to download the entire base package with it. If I could find out what the setup program does to get it working, it might help too.
Any ideas? Any help would be greatly appreciated.
P.S. Please forgive how vague this post is, I don't have the machine in front of me right this instant.

I did some research and found that the drivers for Linux are in the Realtek site (very hidden though ) at this URL

Hope this helps.

Broadcom 802.11n Network Adapter not working on Windows 7 64bit

As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium. I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve. This however just cropped up after two months of successful use. Yesterday it started failing to connect to the internet, telling me that no wireless connections are available. I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360. I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared. When I reboot my laptop, all I get is a notification that no networks appear in range. If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time. I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that

Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
already connected to a wireless network on startup.
I.a. Disable Device sleep on disconnect
Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
well.
Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
2. Double-click on Network adapters.
3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
4. Click on the Advanced tab.
5. Select Device sleep on disconnect.
6. Set the Value to Disabled.
7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

Thunderbolt Network Adapter not working after yosemite upgrade

After I upgraded to Yosemite, my MBP Retina 13" doesn't see the link on thunderbolt network adapter. The wireless is totally unreliable and freeze every few min for 1-2 min which is long enough to disconnect any sessions. Turn off and on of wireless works and recovers but it's royal pain. Any suggestions?
I scheduled call with Apple 3 times today. They call me back at the scheduled time and immediately tell me that I missed their call even though I pickup on 1st ring. Been waiting in their support queue for more than 30 min now and no one is on line yet.

the link provide above leads to http://plugable.com/2014/10/31/os-x-10-10-yosemite-ethernet-adapter-problems-we- can-help
...but these seem to be all 3rd party USB ethernet adapters and nothing to do with the Thunderbolt adapter of the thread - or am I missing something?
I have the same blooming problem, it seems to be totally hit and miss whether the adapter works or not.
I thought is was a faulty adapter, so even bought a second one for my MacBook Pro, so a bit more profit for the most profitable company in the world for a non working device. My ethernet cable works fine to an old apple USB adapter but is 90% useless with Thunderbolt.
Renewing the DHCP lease occasionally works, but totally unreliable, at the moment it fails.
Still looking for a reliable solution.
Come on Apple, please sort this out, you have a connector policy of turning everything you can into adapters and dongles rather than building them in, so you end up with a slim laptop and a bag of adapters to carry around, and then when they don't even work - doubly annoying.

Network adapter not working Win 7 64 bit boot camp

I have a late 2013 MBP r 15-inch 1 week old
Installed Windows 7 through boot camp and loaded the windows drivers and everything works fine except the Internet, when troubleshooting Windows said there is a problem with the wireless network adapter.
When checking in the device manager, I have only 1 unknown device and it's a Intel HM87 LPC conttoller 8c4b, I've tried updating the drivers to that with no help, still unrecognized.
Help please!

Forgot to mention that the only listed network adapter is the Broadcom 802.11ac Network adapter and it says it working fine (no errors).

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

G5 dvi to vga adapter not working

DVI to VGA adapter not working with my G5 Dual 2.3 GHz Power PC. I am trying to use a VGA Monitor but can not get a signal. I also am using a Dell with a DVI Input and that works fine using a DVI Cable from my G5 to the Dell u2410.

Bad adapter?
The G5 ports are DVI-I. Any good DVI-I to VGA adapter should be fine.

StarTech Adapter not working with Dell Inspiron 15, model 3521

Side Note: I wrote a reply to a thread that was from 2013. I do apologize because the link was sent to me by my bf and I did not realize how old it was. Since my reply has to be approved I can't delete it.
Current Issue: StarTech Adapter not working with Dell Inspiron 15 model 3521
I bought my Dell laptop last year and at first I did not realize that it had only one audio jack (combo, as the specifications manual says), I only noticed when I was trying to plug in my Ozone Rage ST headset.
I searched online threads and found out that I needed an adapter and most people mentioned Headset Buddy. I couldn't find any adapters for sale in my country (or employees didn't really know what I was talking about) and since Headset Buddy is a bit expensive, I decided to try StarTech Headset adapter for headsets with separate headphone/microphone plugs - 3.5mm 4 position to 2x 3 position 3.5mm M/F www.amazon.com/.../ref=cm_cr_pr_product_top.
It arrived today and let me tell you that I can't make it work. I can hear everything but I can't get the external mic to work or even be detected. I have always used my headset (mostly for gaming) and I prefer to use my external mic rather than the internal one. First I connected my headphone and mic jacks to the adapter and only after that did I connect it to the laptop combo jack. I also tried vice-versa. It didn't work, regardless of the order. I even tried with a different headset and it still didn't work. What else can I do?
I have also found a thread on Dell forums saying that Headset Buddy doesn't even work on Dell Inspiron 15, model 3521. So since it doesn't work and I'm assuming StarTech doesn't, either, what am I to do/buy?! I am getting extremely frustrated and I'm very disappointed with Dell because the brand should have included with the laptop a proper working adapter for these situations and not make its customers buy an extra accessory to make whatever working gear they already had function. It just doesn't make sense to me! Either make the changes work properly or simply don't touch anything. I spent some of my savings on this laptop which, overall, is great but now I am being forced to spend more on an item to allow me to use my headset. I am running out of options here and even Dell can't seem to tell its customers with 100% certainty what really works for this specific model.
If I can't make the adapter work, I just hope I can return it, otherwise I'll end up with no refund and with a piece of equipment I have no other use for!
Any thoughts?

Hi,
Thanks for your reply.
This is the first time I was forced to buy adapters such as these so I don't know if I'm doing something wrong or if there's anything else I can do to make it work. When I plug the adapter to my Dell, the laptop presents me with several options such as: headphones, headphone, speakers, skull candy headphones, etc (maybe some may have different names but since I see them in Portuguese, I'm not quite sure how they appear for someone who has the computer in English), I have picked different options and it still doesn't work, the only noticeable changes are sound quality related, I guess.

Did you do the Reset Network Settings as I described above?
There is no way to go back. You can try reseating your nanoSIM or replacing it. Or call your cell provider and have them check the provisioning on your phone.
Or Restore your iPhone from your backup in iTunes.

Wrt610n wireless network does not work after firmeware upgrade

Hi
I just updated my Wrt610n hardware version 1 to the newest firmware, it did finish with sucess, I did factory reset reboot and reconfig. But the wireless network does not work , cant connect computers to it. Did downgrade the firmware to the same it was and restore my settings but still wireless does not work. But router works fine with lan. Any suggestions? maybe the firmware tosted the router?
Regards
Stefan

Update -
After last reset and reupgrade with the newest firmware for hardware version 1 I could config the router and connect 2 computers with wireless - but only for about 15 mín - then they lost connection and could not reconnect.
I did then get the newest update for hardeware version 2 - just to try and upgraded with that and got success, and now I have reset the router again and config it and those 2 computers are connected and have been for 1 hour now. So seems to be working - is it okay to have the firmware for hardware version 2 on my version 1 router?
Any thought what is going on - could it be that the other firmware had not loaded compleytle or?

My hdmi adapter not working anymore, no physical damage. Solution?

My hdmi adapter not working anymore, no physical damage. Solution?
Strange is, that i used it several times, it worked fine. Then wothout any reason (like software updete, etc) it just stopped workung, no sync.
I have not changed any parameters of my TV or Beamer.
Hardware:
Ipad 2, Apple Ipad HDMI Adapter, Samsung P2770FH, Optoma HD 65.
Thanks for any help.

I've only used mine a couple of times without any problem, but due to the thinness of the iPad, care has to be taken in inserting the adapter. Slightly wrong angle and it won't go it.
I had a laptop a few years ago where the USB connector failed. I had it replaced under the warantee, The service man told me it was not an uncommom failure on a laptop due to people "torquing" the USB socket while inserting/removing USB items. I have much the same feeling when inserting either the charger cord or my HDMI adapter.
From your description, unless the HDMI adapter failed internally, it sounds like the socket is causing the problem. A few days ago we watch our first movie from the iPad via my ATV2 and "Air Play". Worked great so I don't plan on using the HDMI adapter much at all in the future. Yes, it is a $99 solution, but it works for me. Of course, I already had the ATV2. I doubt if I would buy one just for this abiliity. If nothing else, it seems like a trip to the Apple Genius bar is in order for maybe a replacement unit.
However, with iOS 5 coming out with supposedly total mirroring, it might be worth thinking about getting an ATV2.
