If you don't want to replace the cable or install a new jack, you have a few of options: Glue it into a coupler or a short extension like one of the following (with the coupler you will need another short run of cable on the other side): Repair it with a zip tie. Use this guide for instructions: ...

It's entirely possible to cut off the plug and install a new one, but you will need a crimping tool. It's about $15. The thing is, your local store will probably charge you more than $15 for a cable - even if you buy it online, it'll probably be close to that when you take shipping into account. Therefore, it's cost-effective in my opinion, even if you only ...

In short, no. The switch should keep track of which MAC addresses can be reached on which ports, and it then only sends packets out through the correct ports. There is a limit to how many MAC addresses a switch can remember, though it's usually not an issue unless you're operating extremely large networks. Furthermore, most consumer routers are actually a ...

Wikipedia has pinouts for a gigabit crossover cable. Note that while Auto-MDIX is an optional feature of the gigabit ethernet specification (IEEE 802.3-2008: "Implementation of an automatic MDI/MDI-X configuration is optional for 1000BASE-T devices"), most gigabit ethernet interfaces do implement it, so in most cases you will not need a special crossover ...

I dont see anything in the comments suggesting that you look into udev and its rules which should install eth0. On my system, in /etc/udev/rules.d/75-network-devices.rules, I have the following; # Local network rules to name your network cards. # # These rules were generated by nethelper.sh, but you can # customize them. # # You may edit them as needed. # ...

First of all, your ethernet isn't being managed by Ubuntu. Try ifconfig -a instead of just ifconfig, so you can see all your networking devices, managed or not. If you do see ethX in the ifconfig -a list, the solution should be straightforward, and you seemed to have gotten half of it. The following needs to go into your /etc/network/interfaces file: ...

The first device under 'Other devices' is an "Ethernet controller". So it is in your list of devices. It is just not yet recognised until you install the right driver. Right click on that "Ethernet controller", select [properties] and open the tab 'Details'. Move a few centimeters down and select the property to "Hardware IDs". You now get a screen with ...

You don't: Auto MDI-X is built into the Gigabit Ethernet spec. The endpoints will auto-negotiate and take care of those communication issues.

The bandwidth specs on your router's spec sheet are in Megabits Per Second. One byte contains eight bits. To calculate the number of Megabytes Per Second, the unit of measure you are reporting, simply divide the Megabits Per Second spec by 8. Your router only has 100Mbps ports. 100Mbps is roughly 12.5MB/s. 11MB/s of throughput (what you are getting) is very ...

Most modern computers come with an ethernet adapter that has the capability to connect to another ethernet adapter without a crossover cable. This is called Auto-MDIX. Simply connect the network interface from one computer to the network interface on the other computer. Once they're plugged in, there might be some sort of automatically-configured network ...

Yes, this works. In fact it's how a lot of testing of 802.11 gear gets done. There's one critical thing you're missing from your described setup, and that's sufficient RF signal attenuation so your receivers aren't completely overloaded by your transmitters. You generally need about 60 dB of attenuation between transmitter and receiver. If you have the ...

Good. Then you do not have DNS nameservers. Add these two lines to /etc/resolv.conf: nameserver 8.8.8.8 nameserver 8.8.4.4 and it should work.

The feature you are looking for is VLAN isolation. It is not a common feature in "home" routers (because few home users need VLANs, let alone know how to set them up), but my Small Business router from Cisco does have the ability to set up separate VLANs and restrict them from communicating with each other. (Specifically, it allows setting a specific VLAN to ...

How-To Geek has provided a nice, step-by-step tutorial on how to use your Windows 8 laptop as a wireless access point.

Actually, I did some more poking around and found some answers myself, and it's really easy. There are two ways to do it: share the connection from Windows to Ubuntu, or from Ubuntu to Windows. Importantly, only one of these will work at a time, but doing both won't break anything. It just won't share the connection until you reverse one of them. Windows 7 ...

Your crossover cable scenario is how ICS should work. You'll just have to make sure you don't manually assign an IP address to the LAN connection on your Windows machine and let ICS do that for you, i.e. you should enable ICS on your Wireless connection and select the Wired/LAN connection as the destination and the latter's IP address should be changed for ...

You should be able to do this with a standard ethernet cable if you bridge the connections in network settings. This post on MSDN indicates you should be able to do it with a normal patch cable and has instructions to follow.

For a quick fix, I've successfully used a small piece of paper to wrap the 3 non-conductor sides of the socket and then insert the cable into the socket. Leave some paper extending outside the socket so you can prevent the plug from just pushing the paper into the socket. This hack can work for years, if there is not a lot of movement of the device or ...

I'll preface this by saying I've never actually tried this, but I can't see why it wouldn't work as such: Hook up the wire (since they're Gb ports, you shouldn't need a crossover cable to get Link). Configure the adapters to be on the same subnet (say 10.1.1.1 and 10.1.1.2, mask 255.255.255.0). Only one of them can/should have a gateway, and if you need to ...

Either you have a modem or a modem/router if it's a modem/router it'll allow several PCs connected at the same time usually these have an internal ethernet switch and several RJ45 sockets, allowing you to connect up-to 4 PCs If it's a modem only you'll have to get a router or modem/router to augment or replace it, or configure one of the PCs to take over ...

It’s not clear what brand/model mode you are using, but if your modem is being connected to your PC via an Ethernet then there is a good chance it has a DHCP router setup in it’s firmware. If that is the case, you can just buy a simple Ethernet hub/switch, connect the modem to the hub/switch on one port and then have the other computers hooked up via other ...

There are a few solutions available, but all will have two features in common. There will be a computer with at least 2 network interfaces e.g. ethernet and WiFi or USB (for the latter you may need a bridge adapter and specific network drivers). That computer will serve as a NAT router for the other computer(s) connecting through that. So technically you ...

You need a crossover Ethernet cable. The crossover cable allows you to not use a hub or switch to connect two computers together like your Raspberry Pi and laptop. When you buy one, I suggest you mark it with a label or a permanent marker on each tip so you know it is not like the others.

You can always cut the broken end and add a crimpless plug. Here is an example. They are more expensive than a crimped end, but perfect for an emergency. Different brands/models have different capabilities such as self cutting the wires.

The simple solution if it's available would be to use one of the PCs to create an ad-hoc Wifi network, and then use that to bridge the connection to the wired network. Obviously this requires a Wifi card in one of the machines you're using on the network. The Microsoft guide for doing so is here: ...

The signal will be fine running over cat6A or cat5e. The order of pairs and interface (RJ45 or 110 punch) are identical for both cables. The only real differences are in how the twisted pairs are arranged inside the cable for the purpose of carrying the signal. Cat5e is capable of 1Gb, but is less resistant to interference, length of run and sharp ...

I have a similar issue with Win7 wireless connectivity, occurring randomly when disconnecting from one network then connecting to a different network. The Tray icon would freeze. The Issue appears to minimize when I close any apps using the network, such as internet, external USB drives etc. Also seemed to occur less when using Task Manager open in the ...

Actually, you don't even need a crossover cable. Modern year 2000-ish network cards can support switching without a crossover cable; it's all internal. Just plug-em' in and go. All of the networking will be automatically handled.

WiFi uses CISMA CA (collision avoidance) so there would be no need for a switch in such a configuration. The WiFi devices would be listening to the spectrum before sending data.... I think the only issues would be related to unanticipated resistance & power going through the wires that may reduce quality / cause issues. I would be interested to see such ...

The solution is incredibly simple. Both of you should install Hamachi which is a free software VPN that will allow you to add users to your VPN network and they can communicate with your PC directly via this connection. Hamachi will either work via direct connection between clients, or if this is impossible, it will relay the connections (very similar to how ...
