The Debian net_device header was changed in kernel version 3.8 and since some drivers have been experiencing issues. I ran into the issue with an ethernet card from the same family on Ubuntu 14.04 and these commands worked for me: wget https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/04/compat-drivers-2013-03-04-u.tar.bz2 ...

I found a different MS Support article helpful fixing this issue in Windows 7. It basically explains that you can: Go to the Start menu. Type view network connections in the Search programs and files box. Choose View network connections in the search results. Press Alt and go to the Advanced Options > Advanced Settings... menu item. In the Advanced ...

These things completely wiped out my radio reception from about 3 to 20 MHz. This won't bother most people but as a ham operator it was completely unacceptable to me. And I don't understand how the FCC approved these things when they put out so much RFI.

I'm not a tech whiz, but I am having issues with Ethernet or power also. In talking to an electrician, he stated that these units work best if they are both connected to the same 110v leg of the inbound power. electrical power coming in arrives with two 110v legs, and a ground. To get 220v, the two legs are then used are used with the ground. As the 60 ...

I think I have figured out the issue. In the meantime I had also observed at times the devices attached to the second wireless router get internet access momentarily (probably whenever they were reattached after the router has been disconnected for sometime) but that was not consistent. This suggested there could be some issue with either the switch ...

Send a broadcast If you don't have any information of the other end, just send a ping 255.255.255.255, it will send a broadcast ping (IP 255.255.255.255) with broadcast MAC address (FF:FF:FF:FF:FF:FF) which will be sent to all devices on the network, even if you are connected to a switch (which don't filter those requests, of course).

NMAP can scan your network and tell you a lot about what is on your network, including MAC address. It might even be able to tell you just what that unknown device is. Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as ...

Having internet sharing enabled may do this on Mac OS. Check in System Preferences, Sharing, then if Internet Sharing is enabled over the ethernet interface. Disabling it may solve your problem, although you will of course lose the shared connection. [was having the same problem, this was the reason]

Yes - It sounds like what you are trying to do is setup a WiFi bridge using your laptop. Check out this video for a general Windows guide: https://www.youtube.com/watch?v=IqKdBj537cg I would still recommend getting a WiFi adapter for your desktop - you can find USB adapters for

simplest answer is yes. Add the USB ethernet adapter to your computer, then set either the onboard, or the USB to be shared, and it will work the same way.

Yes, it will work. You will get 2 Network Adapters in your OS and will be able to use both simultaneously to do what you need/want to do.

You need a router. You need some device to masquerade for the devices on your internal network, otherwise only one device can have Internet access.

If it is a hub you need to have either static ip addresses for those units or use a router with dhcp enabled. My guess is that this is a corporate setup. If that is the case that port may be blocked when all the units are connected due to the fact that ten devices are connecting where there should only be one.

In general, hubs are few and far between to find nowadays. But assuming it is indeed a hub (and not a switch or router) then you can select any port you want to be your uplink (in your case, WAN) port. I usually pick either the lowest or highest port (furthest left or right of the ports just to make it easy to find later on). At the other end of that cable ...

A "Null modem cable" is the standard RS232 cable that can be connected to the COM port. It is also possible to configure switch using a standard Ethernet cable. see the page 34 of this user guide

The docs say that you can connect using the COM port (RS232) or through Ethernet to be able to manage the device through a number of different methods - web GUI, console etc. https://www.mtmnet.com/PDF_FILES/3C16980_MgmtGuide.pdf - pg 33. To be able to use Ethernet to access the device web GUI you need to initially configure the device to have an IP ...

Yes, that’s possible. Open the “Network and Sharing Center”, select “Change adapter settings” (on the left). In the view that comes up now, select both your wired and wireless connection, right-click on one of them and select “Bridge Connections”. A guide with pictures is also available here.

Basically, it's for TCP/IP communications over USB. Why you would want to do this varies, but usually it's because a specific device requires it. Some notable examples are the BeagleBone, USB tethering with modern Linux kernel based phones, and possibly some amateur radio devices utilizing USB (likely for packet radio). To the best of my knowledge, usb0 is ...

Quite simply you have connected everything up wrong. connect your modem to your router as follows: Modem -> ethernet cable -> router "WAN" socket Connect your PC to your router as follows PC (IC Plus 10/100/1000 adapter) -> ethernet cable -> router "1" socket You could, in theory, then connect other ethernet devices to router ports 2, 3 and ...

Ethernet switches do not broadcast all traffic to all ports. A unicast exchange between two hosts on two separate switch ports will not be seen by a listening host on a third switch port under normal operating conditions. More expensive managed switches, with enterprise functions such as VLAN support often have port mirroring features, that serve as a ...

If the on-board network port is unplugged and your PCI network card is installed correctly you should not be encountering a problem. Ensure that you've removed the Ethernet cable from the on-board port. Since you no longer need the on-board port, it may be simpler to just delete it. See below https://kb.wisc.edu/helpdesk/page.php?id=26681 (the on-board ...

Turns out this was neither Ubuntu's nor Windows' fault, just my ISP's DHCP doing a bad job. Putting a router between my PC and the transmitter made both network cards work flawlessly, on both systems.

It really doesn't make a big difference - It'd be only two ethernet ports away. If you need special features like subnets, your serving machine being the DMZ or it having a different gateway or being on another broadcast domain, then connect it directly to the router, if not, you can leave it directly connected to your switch and avoid having the traffic to ...

There are quite a lot of things to check:- Are you using the correct uplink port on the switch to connect to the router? Most Ethernet switches have LEDs to show connectivity: are these lighting? Are you using straight, not crossed cables (though you may need a crossed cable for the access point)? Leave the wireless access point disconnected initially, as ...

I found out that the key to working with MAC addresses is the ARP table, a table that links neighbouring IP addresses (IP addresses on the local network) to MAC addresses. All you need to do is use ip neigh add to link your router's MAC address to an IP address, then route via that IP address as usual: #!/bin/sh DEV="eth0" ROUTER="192.168.0.1" ...

Is the new one a "managed switch" by any chance? May be that could be one reason why it will not let any traffic through unless it is told to do so. Is your TP link modem's internet line connected to the "up-link" port of your new switch? Share the switch model number as well.... only then can we move further on this.... Is the copper cable that connects ...

Try do this in /etc/network/interfaces : auto lo iface lo inet loopback #auto eth0 #iface eth0 inet dhcp Then reboot. Then configure network from graphical network manager (which in tray). Set dhcp, if your router (or internet provider) supports dhcp. Also maybe you changed physical address of network card, so internet provider bans you.

Speed is the major factor between them but also they help to reduce things like crosstalking (jabbering) as with CAT 6 all the separate wires are independently isolated to stop interference. However I don't know how an expensive CAT 5 cable stands up to a cheap CAT 6 cable, as far as I know there is no actual standard for manufacturing quality on cables.

Well, since no one has mentioned it... There is no reason to believe that a particular NIC's line drivers will actually push electrons all the way out to the Standards's maximum lengths. I have had exactly the problem you describe fixed by replacing one instance of a NIC with another instance of the same NIC -- same part number, same lot. I've also found ...

1) use patch cord to ensure the devices are ok 2) look through the cable and check if it's tensed, compressed, constrained, twisted or turned with small radius. straighten it if required 3) remember the time and reliability is money and just replace it
