You're only allowed one link between switches to prevent bridging loops. If your switch is managed and supports LAGs, you can group multiple ports into one logical link.

The maximum possible bandwidth between two switches depends on the features (and possibly the configuration) of the switches. For switches that only speak Ethernet If either switch does not support LACP, there is no advantage in connecting more than one cable. If both switches do support LACP, you can get more bandwidth with more cables, up to some limit ...

During this Offline/Online State that you Can't access any website, On your Console (CMD) try ping 8.8.8.8 If you get your packets back, then try nslookup www.google.gr if you don't get a result, your ISP's DNS Server is malfunctioning. The best thing to do is to set as Primary DNS Server 8.8.8.8 , and 8.8.4.4 , Google's DNS Servers. If you ...

it's not the speed, it's the way it's calculated. Usually, as you initialise a transfer, the counter starts from right then, ignoring any negotiation time. A tiny file spends most of its upload time in the initial negotiation, compared to the actual data transfer. With a larger file, this initial mis-calculation is gradually absorbed by the overall ...

The first answer on the question you listed is the right one. You need an Access Point.

You just need a wireless router that supports AP mode, lets you turn off its DHCP server, or can be set to a seperate DHCP range. There's also standalone access points - which might be the cheapest option. In my case I have a primary router (connected to a ONT for fibre optic internet) connected to a Asus router that has AP mode support. In the past I've ...

The Internet Protocol does not have an inherit way of disclosing the address of either party If you have control over those endpoints you could set up such as service, or simply capture an ICMP echo (ping) on the remote endpoint to see what IP it's being presented with Another solution would be to use netcat to open a simple server and connect to it, when ...

I presume you are talking about resolving the server name inside your LAN. For this to work, you must have at least one of these: A working DNS inside your own LAN (or on a companion LAN, performing this job for your LAN too). An entry in the client /etc/hosts file, associating name and IP address. A working samba server on the ssh server, where you have ...

It very well could be a double NAT issue. I have seen ISP’s provide a private IP from their modem as it also acts as the router. Could this be the case with you? The WAN IP that you see on your router what is the first octet of the IP? if it starts with 192.168.x.x 172.16.x.x -172.32.x.x 10.x.x.x These are non-routable private IP address and will ...

I was having the same problem, but initially it was only around 30 seconds. But when it jumped to around 2 minutes (for some unknown reason), it got so annoying, I had to find a way to solve it. I have created batch script which tests the network by seeing if it can ping the target machine, if it can, it maps the drives (if unmapped), otherwise, it deletes ...

You should just have to turn off the DHCP server in Tomato and turn it on on your Windows Server. You don't have to "point" anything at it. The way DHCP works, is it sends a UDP packet to the broadcast address for the subnet, so as long as the server and clients are on the same subnet it should "just work."

Use iw device scan to show all information about currently visible networks. The output has more than an entire screenful per network, so use grep to trim it down: $ sudo iw wlan0 scan | egrep "^BSS|SSID:" BSS 24:a4:3c:9e:d2:84(on wlan0) -- associated SSID: eduroam BSS 24:a4:3c:ae:df:83(on wlan0) SSID: Example multi-AP network BSS ...

This all sounds like 802.11n network voodoo to me. The reality of 802.11n is not all devices support or behave correctly when using it. The best advice would be to get a new router if you can. Or try to use 802.11g on you phone and laptop to see if you get a more stable connection. The other idea is to see if your router is set to mixed mode which attempts ...

Because when you changed your computer name, the other computers cache (locally stored password) is wrong as it's pointing on your old computer name. Example My computer, A shares files on the network. Computer B connects to A and types in a username/password. This username/password is now cached locally and computer B no longer have to type it in each ...

Connecting your cable modem directly to a PC is sometimes a necessary troubleshooting step - to ascertain whether problems are with your router or not, for example. Assuming this is a cable modem, and that it behaves like mine: Cable modems will only recognize a single device behind it - if you want to share the connection, a router does that and is ...

There's no way to guarantee 99.9% uptime in your configuration. It would require network connection redundancy, clustering, etc... Anyways, letting your PC run without rebooting it for 4-8 weeks sounds like a bad idea. You could rent an FTP server from any major web hoster just for the 2 months you need. It would give you better uptime than any homemade ...

Your landlord cannot access your network behind the router just like his ISP cannot access the network behind his router due to Network Address Translation. He is basically your ISP and has assigned you an IP address. All he can see is your router as long as you have it secured. You can however, see what is on his network as he is outside the security of ...

My question is what Hotspot Shield is doing to connect to vpn The real answer to this is: it does not go through your ISP. Let me elaborate. Your VPN, to be effective, should allow you to connect from outside your home, and then surf the world having, as IP number, your home number; further, it should encrypt your communications from wherever you are ...

Most of the adapters do offer encryption, please check the model you are looking at before you purchase it. Also, the signal does fade even over a house distance, you may be able to pick the signal up at the street, but I wouldn't suspect you would be able to go much further than that.

Solved! Thanks to eibgrad at the DD-WRT forums. Here is his answer: (Source: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=277001 ) It's just a clever hack/trick. There’s actually TWO important extra routes the VPN adds: 128.0.0.0/128.0.0.0 (covers 0.0.0.0 thru 127.255.255.255) 0.0.0.0/128.0.0.0 (covers 128.0.0.0 thru 255.255.255.255) The reason this ...

This is probably due to the Network interface driver issue. I would recommend you to uninstall the Network interface driver: Download recent network driver from the vendor site. Press Windows key+r > type devmgmt.msc > select the Network interface > right click and Uninstall > now, double click and install the downloaded network interface driver and check ...

Jim G may be right for some switches, except that many, especially linksys and Cisco, use spanning tree protocol to manage link redundancy and infinite loops, so it usually isn't a problem. As a network and systems admin you'll have to decide whether it's relevant for your situation. We have 5 servers, each handling a different subset of applications. We ...

Is there any actual advantage to having more than one Ethernet cable running to the switch from the server? Yes. Adding extra cables from one server to its switch may be useful in two ways : extra bandwidth : if the traffic to your server is heavy, there may be a bottleneck here. Note that servers have limited capacity : a file server cannot send ...

A /24 is equivalent to a netmask of 255.255.255.0, so you can't stuff two networks inside the 192.168.10.0/24. You should tell the router that it has 192.168.10.0/25 (a netmask of 255.255.255.128) for the first network, and 192.168.10.128/25 for the second network.

Set a route. http://technet.microsoft.com/en-us/library/bb490991.aspx Enter command line and write a route, probably somewhat like this: route add 192.168.1.0 MASK 255.255.255.0 192.168.1.17 where the first ip is your private network and the last ip is the ip of your network card (can be looked up with ipconfig) If you want a route that survives a ...

Without being the admin? Probably not. There's a few fundamental issues here. Modern networks use switches, and switches only send data to the port where they're needed. If you specifically knew where to watch, and sneakily replaced a switch with a hub, and both you and the user torrenting were plugged in or you had the functionality for mirrored ports on ...

Your solution is below; Kill the long "restoring network connections" at logon (defer=ghosted connections) [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider] "RestoreConnection"=dword:00000001 ;(0=no attempt, you must click it) "RestoreTimeout"=dword:00000005 Ghost the connection if not responding within RestoreTimeout ...
