Macbook Air 2012 / Connecting To Ethernet Network?
Sep 3, 2012
I'm trying to connect my macbook air to a university Ethernet network. I'm using the apple thunderbolt to ethernet adaptor to connect, and it registers a connection in the network preferences, with an IP address and subnet mask number. However, it wont fill the router name, the DNS server number or the search domains fields.When I use google chrome to load a webpage it doesn't load, stating that a DNS lookup has failed.How do I get connected?

When I create a virtual switch on hyper v, i lose network connectivity and the default gateway is missing I have to manually put the default gateway in and disable and re enable the network adaptor each time the server restarts in order to get network connectivity. I am running windows server 2012 Hyper V Virtual Ethernet Adapter loses default gateway server 2012

My Network is gone from my list of available networks on my MacBook. I use s NETGEAR router, my network name is simply "NETGEAR" i have never named it anything else since installing this over 4 years ago. I have unplugged the power cord, waiting several minutes before plugging it back in. Also tried unplugging both the cable and the power cord. The router has no small "pin hole" that i can see in order for me to try to re-set it this way. It has literally disappeared from my Mac. Do i need to re-install using my NETGEAR cd?

is it possible to set up communication between my desktop Windows 7 machine and my MacBook Pro so that I can access files stored on my windows pc via my Mac?I have most of my music/movies stored on the desktop and want to be able to access them around the house on my mac.Tried searching for a way with no luck,I vaguely remember having had a connection set up automatically when I had a windows 8 laptop, so I would imagine its possible to do this.

Macbook Air, OSX 10.8.1, on a home network under a Cisco/Linksys WRT110 router, internet via Optimum cable modem TM822G. Other PCs are W7 and XP, plus an iPad, iPhone & droid.
This mixed setup had worked fine until Optimum (Cablevision) replaced our aging cable modem. Since then, whenever the Macbook attempts to connect to the network it kicks all others offline. The Macbook itself can't get online. The network created by the router remains OK, but the connection to the cable modem & internet is lost.A couple of years ago, when a W7 computer was first introduced, it had the same effect, and we determined that turning off IPv6 on the W7 computer resolved it. But since then, we got a new router and it had no problem with IPv6. I mention it only because the behavior is the same. But in this case, it's a new cable modem that was introduced. Now the Macbook Air, which has been working fine on the network, crashes internet.Unfortunately, the Airbook is a high school issued piece, so we can't turn off the IPv6, due to access restrictions; not that that would've necessarily done it, but it's hard to troubleshoot when you can't make changes.So the two pieces involved in the problem are the two pieces we have little control over.

Running OS X 10.5.8 on an old MacBook Pro on a wireless network. It might be relevant that I recently upgraded the wireless router and the DHCP-assigned IP addresses changed. Before that, everything worked reasonably well.
I can connect to the MBP from Windows 7 computers on the network, logging in with a user name and password, and access the files there as expected.
But the MBP disappears from Windows Explorer after a few minutes. I can usually add it back (always checking the box to remember it) but it just keeps disappearing. Sometimes when it disappears, I can't add it back and when I try, Windows Explorer says, "can't find."
How can I get this share to stick?

I have a belkin N300 router that works decent most of the time, but anytime my roommate connects with her macbook pro the whole network becomes slow to the point of uselessness. If i block her computer using mac address filtering, the latency and download speeds are right where they should be, but as soon as i allow her back on ping jumps to 800-1000 and DL speeds drop to under 1mb.

I recently had to completely gut my computer and start from scratch, reinstalling windows xp, and all hardware. I only have a basic knowledge of computers, and their inner workings. I had my modem connected to my computer via ethernet, and i enjoyed fast browsing. Since the rebuild, i can only use the usb (and it's sloooooow!). I have learnt all i know about drivers because of this issue.

I've recently bought a new computer with a wireless card. However, the wireless signal is terrible, so I'm looking to try and get my PC plugged directly into my rooter (or by other means).
Do I have any other options of doing this, other than a wire from my rooter to my PC. Is there any other solution which enables me not have to plug into my rooter directly?? (as my rooter is in an awkward spot and has to stay there). Can I plug into an ADSL port for example? Or any other alternatives???
I'm a bit of a newbie when it comes to anything to do with networks, internet access, LAN etc etc.

I have some unused 10G NIC's and want to see if there's a way to install them into a computer and turn that PC into a switch. I need to run Windows based software for driver support of the NIC's, such as Server 2012. This is a picture of what I am hoping to accomplish:
[PC1] -----10G------[PC2]------10G------< Hardware Switch >
| | | | |
1G 1G 1G 1G 1G
| | | | |
[PC3][PC4][PC5]......
As you can see in the simplified picture above, I have a real switch which has a single 10G link that is connected to PC2. I would like to add the 10G cards to PC2 so that I can create a "switch" of 10G ports on PC2 which I can then hook up other clients (such as PC1 in the above picture).
PC2 needs to provide network access and internet access to PC1 (and other PC's connected to PC2 - not pictured).
The rest of the clients on the network are connected to the regular gigabit ethernet ports of the hardware switch (including my router which is 192.168.1.1).
I looked into Windows Internet Sharing, but for that to work, I need to connect the router to PC2 above and for other considerations not described above, it is not physically possible for me to do that.
Is there software I can run on PC2 that will turn all the NIC ports of PC2 into a "switch"?

I had one straight through cable connecting one switch and a pc in my office. The cable is approx 90 metres in length. The cable has been cut in between by rat. Now can I join those 2 cables by a coupler, if so will it increase latency, what type of crimping is required, straight through or cross cables. I think 2 cross cables connected by a coupler becomes straight.

Basically I bought two ethernet adapters from amazon and have connected them up properly to the router and my laptop through my homes plugs. For some reason my laptop cannot pick up any internet signal from them displaying 'no network access'. When I've run the troubleshoot it occasionally will say that the IP address is not valid. I've tried a variety of different settings but cannot seem to get it to work.

My son is getting a Cyberpower PC Black Gamer Ultra Gua250 Desktop for Christmas. It comes with only a 10/100/1000Base-T Ethernet. Is there a product I can purchase to connect his pc to our DSL without having to run an ethernet cable all through the house?

I've been trying to use my laptop (Lenovo IdeaPad Y580) as a wireless adapter for my Xbox 360 by bridging the LAN/Wireless networks and connecting the Xbox to the laptop via Ethernet. The wireless works fine normally, but when I plug the Ethernet cable into the computer, the laptop automatically disables WiFi and changes to a LAN connection. It doesn't give any options whatsoever to reconnect to wireless, just forces me to use the Ethernet connection. As soon as the cable is removed the wireless connection returns, but for what I'm trying to do to work, I need both LAN and wireless to be working simultaneously, and the wireless providing the Internet connection. I've also tried connecting the laptop to a router via Ethernet and received the same result, so I'm pretty sure it's something on the laptop that's causing it. Is there a way to change this so the laptop can use the wireless connection while plugged into another device via Ethernet?

Although I haven't looked through all the forum topics I couldn't find anything very similar to my situation. I have a rather large house and my modem/router (Netgear DGND3300 v2 due to DSL) is in the very corner. Given this most of the opposite corner of my house gets either poor or no connection; however, I do have an ethernet cable run across the house through the basement to my home theatre setup. This is where I encounter another problem, I need multiple devices to be connected via ethernet and I also need to have wireless in that same area. In my mind I picture myself connecting a second router to this ethernet cable through which I could have wired connections to all my devices, and a second router broadcasting wirelessly. I'm familiar with some types of wireless bridging, but I'd rather use more of a wired bridge concept if possible, but I've never really seen something like this. The question is, is this possible? Or, what is another possible way to achieve the same results? The only other thing I can think of is to run an ethernet hub from the original wired connection to my home theatre so I can connect multiple ethernet devices and run a separate wireless extender or something, but this just seems pricy.

I just installed windows 7 into my computer and I need to verify my copy of windows. I tried connect my Ethernet wire from my computer to the wireless router but it's not connecting or registering. The wireless router is a WRT54G and I can access the device ip for it but I don't know how to assign an IP address for the new computer. I already had a computer (wired) and a laptop (wireless) connected to the router. I'm using a straight trough Ethernet wire Doing the steps in the sticied post below didn't work because typing ipconfig /release didn't work?

I have a home lab. I am trying to connect a 1710 to a 2610 with just using the fast ethernet ports. I understand that serial connections and t1 csu/dsu connections use clocking, etc. How can I configure FA ports to do the same AND be routable?

I have Netgear N300 (DGN3500) Wireless Gigabit ADSL2+ Modem router.The Router has a phone socket (that is RJ 11 socket) to connect to the Internet. But in my home I have Ethernet socket on the wall. That means the Internet is coming through Ethernet cable. How to connect my ADSL2 Modem router (with the phone socket) to the Ethernet? I bought a ISDN-DSL (8p4c-6p4c) connecting cable and it is not working when the router and Ethernet are connected..I tested my router at one of my friend's place where ADSL connection is available and it was working when directly connected to ADSL line. Unfortunately at my home I don't have ADSL but Ethernet connection.

We are using MS System Center Operations Manager to monitor network devices. We are trying to monitor our Cisco ASA 5525-X firewall interfaces.
We have a generic management pack installed that seems to work for parts of the 5525. We can see performance info for IF-4 but none of the other interfaces.
Our Management Pack is a generic Cisco Adaptive Security Appliance Version 9.1(1) management pack.
Is there a management pack that is specifically for this Cisco firewall?
