U330 Ethernet not working, wireless works fine

I have an Ideapad U330 that will not get online using ethernet in windows. Before you ask, no it isnt my router. When I use an Ubuntu bootable disk, the ethernet works fine and I can surf the web without issue. I reformatted and installed windows 7 x86 (It had windows XP previously and the ethernet didnt work there either), installed all the drivers, and updated the BIOS, the ethernet still does not work while the wireless works fine. I thought this was a hardware issue until the ethernet worked with no issue in Ubuntu.
Solved!
Go to Solution.

Alright well I booted it up in Ubuntu again to get the details, got an IP of 192.168.1.142 and DNS of 192.168.1.1. When connecting through Windows, I get an IP of 192.168.1.198 and DNS of 192.168.1.1. The only difference that it pulled up that was different from Windows' ipconfig /all is that it pulled a slightly different IP.
But, lo and behold, manually putting in the IP pulled from Ubuntu worked. But each time I try to go back to automatic IP in Windows it keeps delegating it to 192.168.1.198. Is there any reason why it keeps doing this? I would imagine that the router could have a setting having that out of an accepted range, but since that's the only IP it'll obtain otherwise, I'm wondering why that is.
I guess all there is left to ask is whether there's a way to keep the IP and DNS as automatic settings rather than manual. This is a college campus and I'd like to make sure that it wouldn't interfere with other computers or locations, including off-campus locations. Any thoughts?

Ethernet not working, wireless works, with older computer.

Hi there.
I'm trying to set up a new wireless network. Currently it's looking like this:
DSL Modem set up in bridged mode, connected to my Airport Extreme N (Fast Ethernet) through ethernet.
The Airport Extreme is configured to share the Public IP through DHCP throughout the network (192.168.X.X).
Now all this works (after some trial and error anyway). My computers have no problem connecting to the wireless network, or the USB disks I have attached to the drive (hooked a USB hub into the AEBSN's USB port, and attached two disks to that).
(Computers that are connecting to the network are: MacBook Pro, MacBook, iBook G4, iBook G3)
Now what I'm trying to do is connect the iBook through ethernet directly to the AEBSN. I want to use it as a download computer of sorts, but don't want it to degrade the wireless from N speeds to B/G speeds all the time (the other iBook is off most of the time, and the MBP and MB are both N).
When I turn off Airport on the iBook G3, and plug in an ethernet cable which is running from the AEBSN, I'm not getting an IP at all. It ends up with one of those self assigned IP's. I let it sit like that overnight to see if anything would change, but it remained as is.
So I'm trying to figure out why this isn't working. Am I not setting something up correctly? In the end I'm not too knowledgeable on networking, and am hoping someone here can help me out

Have you tried connecting any other of your Macs via Ethernet to the AEBS? If you do that and the other Mac works, then you know it is a problem with that iBook.
If you try it and it doesn't work it could be a faulty cable or something wrong with the AEBS.
Ensure that your DSL modem is connected to the AEBS's WAN port.

WRT610N Wired Connection Not Working; Wireless is Fine

We've had our WRT610N router for about a year, and we've been able to connect via wired and wireless connections without any problem. As of last night, the wired connections are no longer working. We unplugged the cable modem and router numerous times to try and get it to work, but the wired connection is still out.
One item of note, we had a lightning strike a tree in our backyard late yesterday afternoon. I'm not sure how this could possibly have any bearing, but I thought I would mention it.

I've heard a lot of that story, thunderstorms ruining the router configuration. I'd suggest you reset the router to defaults and give it a try. Though it would also reset the settings you have set in there.

Ethernet Broke/Wireless Works

Connecting Apple TV to my computer via ethernet cable now doesn't work. I had it working originally, but I started playing with using an external storage drive and somewhere along the line ethernet broke. Wireless works just fine.
Possible causes:
1. Computer choked during password wakeup from sleep. Chose to force a reboot.
2. Tried using "Libra" a third party multiple library tool for iTunes (before I realized iTunes supports multiple libraries without need for such software). I've since removed everything "Libra" related best I could.
3.???
Things I've tried:
1. Fixed permissions.
2. Reset PRAM
3. Disk utility:repair drive (found some errors)
4. New ethernet cable
5. Restarted Apple TV
6. Removing Apple TV connection in iTunes prefs
7. Deleted iTunes pref files
I'd like to use the ethernet cable obviously because it's way faster than my original Airport.
I haven't had a chance to try connecting the Apple TV to a different computer yet, but I will unless you guys can offer up a solution.
Thanks!!!

Mac OS X (which is what's running on your AppleTV) has a scheme for using network connections. on a regular Mac, you can change the order of the network connections you'd like to use. if you go into the Networking pane in the System Preferences and choose "Network Port Configurations" from the Show: pop-up menu, you'll be able to see a list of the available networking ports. you can drag the network ports in the list to your preferred order for usage. so if Built-In Ethernet is at the top of the list, your mac will try to use the built-in ethernet connection first. if that's not available it will move down the list until it finds a network connection it can use.
unfortunately, you can't change the order on the AppleTV unit. personally, i haven't tried this, but you could set up your Mac to use the built-in ethernet first and see if that helps.
other than that, you can try turning off the iMac's airport all together and see if that forces the AppleTV unit to connect to your mac via the ethernet connection.

New Problem, Old Issue. Ethernet not Working

You may recall this thread: http://forums.verizon.com/t5/FiOS-Internet/FIOS-Ethernet-not-working-Wireless-works-fine/td-p/203838
If you do, well, I have the same issue once more. It's driving me a bit nuts, to be perfectly honest.
About 10 days ago I finally had a stable ethernet connection on my Desktop machine to the internet. 8 days ago I marked the other thread as solved as it was still working and thought that my problems had been solved. Unfortunately, here I am 10 days later and suddenly, without warning, the ethernet connection on my Desktop loses internet connectivity.
I tried turning the router off and then turning it back on, but none of that worked.
Right now it switches between two different states without little indication as to why it switches between them except that it tends to only do it as a I unplug the cable and then plug it back in. The two states are simply connecting to an "Unidentified Network" which is much the same as the problem I had before, and connecting to an "Unidentified Network" with "Internet Access", except, none of the applications that use internet on the computer actually have Internet access even in this state. The Unidentified Network is the key to knowing I still don't truly have internet access.
Windows Firewall is off. It's actually been off for awhile now because I forgot to turn it back on after I initially shut it off trying to get it to connect before. Windows 7 (64-bit) is up-to-date, so that's not the issue either. But something is at issue here and I'm not sure what it is. Since the Wireless works, and the Desktop downstairs works on the ethernet, I can only assume it's something with this Desktop. But I'm not sure what it is or why it's doing this.
Any help with isolating the problem so I can actually fix it and not wait almost two weeks for it to magically work again would be immensely appreciated. Thank you.

Hello there Viafax and Spacedebris!
Apologies for not responding sooner. I decided to take a look at a Windows 7 support forum to see if the issue was something specific to that. After explaining in detail, I got this post and I followed the steps. I posted the information I got and then tried the duplex thing.
The default setting it seems is "Auto Negotiation" which obviously wasnt working.
I tried 100 Mbps Half Duplex and suddenly I had a connection. I can connect to the internet on my Desktop! So I tried 100 Mbps Full Duplex and.... no connection.
So, right now it's set to Half Duplex. But I don't even understand why it would need to be Half instead of Full, or the benefits or disadvantages to either. Right now it's working, but I wish I understood more.
The 192.168.1.25 may have been a typo, since I set the device to run off a static IP of 192.168.1.125, to my knowledge no device on the network has 192.168.1.25
But other than that brief typo, I do believe the rest of the information is as accurate as I could make it. I typed it as I looked for it, so even if it seems odd, that's what it was.

Airplay not working over wireless, works over ethernet?

I posted this in multiple forums in which it applies to.
Just looking for troubleshooting suggestions from my wireless N MBPro, to my wired ATV2. Here is the rundown (all devices running latest updates):
1)used to work just fine with old router
2)airplay works in all directions, from wireless devises to the wired ATV2
3)updated to a much newer N router from cisco
4)now, airplay works over Ethernet from itunes to ATV2 (and iphone4s to ATV2), ATV2 plays music from my MBPro just fine
5) however airplay fails to work from itunes to ATV2 over wirelesss
6)all wireless connections are sound, it is not a bandwidth problem, it literally says "connecting to apple tv" and never stops or connects
7)itunes sees the ATV2 just fine over both Ethernet and wireless connections, i can select ATV2 as an output even when on wireless
8)it will even ask for the password once i select it
So, any suggestions? I just dont know where I am going wrong, somehow the wireless aspect is the broken link. As a side note, all wireless clients and wired clients are on the same subnet.
Thanks for any suggestions or help!

I had the same problem. Disable any IGMP, or IGMP proxy features on your router. As soon as I disabled IGMP proxy on my router everything came up has been working for a while. Lack of driver support on the wireless clients is likely the cause. oh well, at least its working now.

You should probalby contact Netgear

What is the process for connecting ethernet. Have ethernet cable connected to stereo received for internet radio and Blue Ray. However Network System Preferences indicates ethernet not connected and has red dot to left. Note Airport wireless is working.

What is the process for connecting airport extreme ethernet? I have ethernet cables connected to stereo receiver for internet radio and another to blue ray player. The system preference network indicates "ethernet not connected" with red dot to left of this message. The airport wireless works and has green dot to left of it. The stereo receiver and blue ray player do not respond and give message not connect to internet. Thank you. / cfpirate

It worked for me finally. I took out the DNS numbers in airport admin utility, and restarted the airport express. I do not remember putting the DNS numbers in, I wonder from where the airport express got those numbers.
After restarting, it worked.
Thanks!

WRT54G Wireless not working - Wired is fine

You may have seen my last post, where I asked how to set up static IPs within my little network and do a couple other things - thanks for the advice, everything seemed to work great.
BUT I'm not getting wireless to work. I don't think this is a product of my changes, as 1) I haven't been using wireless in the past and 2) I tried changing things back and trying (as a control) and still had the same problem.
Running a WRT54G router, hardwired to three computers (each which also has wireless capabilities). For freedom from wires, tried switching over to wireless. I disabled the "wired" adapters to prevent any interference, and turned on the wireless ones (linksys notebook G adapters and a G pci adapter).
I had the "wired" adapters set up for static IPs within the 10-20 range (192.168.1.10[to 20]). This worked fine. I switched my routers IP to something else, still works. Turn on MAC filtering, and added all six MAC addresses, still good. Then I tried to configure the wireless adapters for static IP like I did the "wired", and used them and got nothing. Tried pinging the router from the comps, and the comps from the router - 1005 packet loss. Went back and set up the adatpers to DHCP (which is still enabled on the router) and still not getting a connection. Tried no encryption, WEP and WPA2 PSK - not working.
My only thought is, I detect like literally 20-25 networks in my area (I live in NYC in a apartment). I can detect my network's SSID, and signal strength is perfect (it should be, all comptuers are within 30 feet of each other ) but when I try to connect, I get the waiting/status bar for like five minutes and then nothing. Are there settings I can use to help optimize my network to deal with all the interference? Are there other troubleshooting things I should try? My last trip here for advice turned out really well - appreciate your help.

hi , You can try a few things here...specially since you have so many wireless networks around you.
bring up network connections, right click on the wireless network connecting and bring up properties...select the wireless networks tab and remove all networks from under "preferred networks".....once done , add your network.You can specify the encryption keys under the association/authentication tab. One more thing,under the preferred networks , you have an advanced button....hit that and select the 2nd option...
on the router you can try and change the beacon to 50 and reduce the RTS and fragmentation threshold by 40 each...these are found under the advanced wireless settings.

Airport TimeCapsule wireless works fine, but iMac can no longer find the time capsule disk for backups.

Hi,
I have a new Airport TimeCapsule that I set up about two weeks ago in combination with a new iMac running OS 10.9.4. It ran fine until 2 days ago, when the TC disk image disappeared from the iMac and Time Machine was not able to back up. I tried to find the TC in Airport Utility and it states the "Airport Time Capsule was previously part of your network. Check that it is still in range of your network and is plugged into a power outlet..." I've tried restarting the time capsule. I've tried restarting everything in order (modem>TC>iMac) and the iMac still cannot see the TC disk.
I've had two other issues that I will list in case they are all related somehow:
1) The time capsule took several attempts to set up when I first bought it. I had to reset the TC several times before I got all the way through the set up process successfully.
2) I tried hooking up my printer to the USB port on the airport time capsule and although my MacBook could see it and print to it just fine, my iMac was never able to see it.
The TC is hooked up to the iMac via ethernet cable. Does any of this sound familiar to anyone? I'm about ready to send the time capsule back and just resurrect my old airport that worked flawlessly for years. This airport TC has been a huge disappointment so far.
Thanks

There are some real issues between Mavericks and TC .. (or just network bugginess!!)
There is a heap of things you can do but it is easier to just run through the whole lot in order. None is necessarily the cure and that is why doing all is important.
The list is in this thread.
Airport Utility shows "unexpected error - please try again" when connecting to Time Capsule
In your case using ethernet can be a problem.. let me say please make sure you have ipv6 set to link-local only in your ethernet setup. I usually only show it in wireless but for you it must be ethernet. The wireless connection seems to be utterly required now for connection.. and hidden away into the airport utility is a switch over from wireless to ethernet. When I made the manual setup instructions above this particular ability (or stupidity) of the Airport Utility was not apparent to me.
So here is typical Airport Utility (AU) v6.. but it is actually working over wireless only. (The v5 utility was wireless + ethernet).
I have an ethernet client on the network that is completely invisible.
Click on the Other WiFi Devices (wrongly named.. it should say other devices).
And you will see the option to choose ethernet.
Then the AU sees the ethernet client and none of the wireless clients.. brilliant stuff eh??
PS this is just a test setup.. never would I have any TC with such an illegal name.. But I hope it shows you what to do.
Fix the names.. most important.. keep them short.. less than 10 characters all the better.
No spaces and pure alphanumeric.

Intel imac - ethernet not working after SMC update

Hi All,
New intel 17" iMac - out of the box works fine using PPPoe, I do and SMC update, and now the connection drops. Its not my ISP, because it works fine on my powerbook, and desktop PC.
I tried reseting the SMC, but when I start the imac the fans kick in and don't stop, and the ethernet still doesn't work.
Any suggestions?
Intel iMac 17" Mac OS X (10.4.6)

I'm experiencing the exact same problem. I just got my 20" Interl iMac back from the apple Store today (took it in for service Sunday because it started getting fatal kernel panics like crazy over the weekend.) They replace the logic board and tonight was the first time I had started it up since Saturday. Immediately got the update window, downloaded the firmware update then BAM... internet connection gone down the drain. The iMac is literally less than 5 feet from our wireless router and the signal strenght is dropping to 1 bar regularly (sometimes losing connection altogether.) This was never an issue before tonight. I've had the iMac since April and it has always maintained a rock-solid connection. In addition, just to rule out the problem being the router, I have a Compaq laptop sitting on the same desk as the iMac and it's wireless connection is over 90%, and my wife is surfing the internet just fine with the Mac mini on the other desk. This is definitely an issue!

Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.
Link to the article: http://www.fastcompany.com/magazine/06/writestuff.html

Software is everything. It also s***s.

IChat AV 4 works wireless but not wired

I've got iChat AV 4 on an iMac running Leopard. When I connect the iMac to my net with Airport, then iChat has no trouble contacting the Apple test accounts (like appleu3test03). When I connect to the net with the iMac's ethernet, then iChat AV fails to make audio or video connections (note, everything else continues to work, including Skype AV if I launch it). It complains that there was a "communication error" and it "did not receive a response" from the other side.
Both the wire and wireless are controlled by the same router. I've tried two, with the same results in each case. When using a Netgear WGR614v6 I let the Netgear handle DHCP. When using a USR8054 I told it to act dumb and let my DSL modem (Actiontec M1000 from Qwest) handle DHCP duties. Again, in both cases the wireless connection to the router allowed iChat AV to connect properly while the wired connection ended in an error message.
What could be going wrong here? Why might the wired connection be failing to allow AV chats?
Thanks for any insights,
...Eric

I would try one thing (this worked for me, thanks to you for telling me that wireless worked)
goto system preferences >> Network
delete the wired connection
create another of the same type with a DIFFERENT NAME (ie. Eth1 instead of Ethernet)
type in the same settings as you had previously (manual IP/DHCP, etc)
try iChat again.
Like i said, it worked for me.
