Two network adapters for a machine to double the transfer speed?

Question

i am new to this. In my scenario, i have a desktop pc running windows 7 and planning to set up a local web server using xampp for big file transfer in the lab. The problem is that,there are 80 machines in lab but my connection to the router(100mbps router) is just 100mbps ie, 12.x MB. when there is a big file transfer, each node will only get a speed of around 150KB... which takes too much time if the files is big enough..

is it possible to have 2 lan cards connected to same router so my connection the router is overall 200 mbps and each node will get 300KB... is there is any possible method???

Answer 1

Doing that will only work if you have a network card and switch that supports link aggregation (or teaming/bonding). This functionality is usually only found in more expensive network equipment. You would need to check your network card's and router's specs to see if they BOTH support LACP (802.3ad).



A way you could work around this would be to access the website via IP address. Configure your web server to listen to all IP address (most usually do out of the box), then simply access the website via it's IP address instead of host/domain name. You could have half your lab access it via the first IP and the second half of the lab access it via the second IP.



Ultimately, I think your best bet would be to simply install some more modern networking equipment in your lab. Something that supports gigabit ethernet. Depending on your network's needs, you could probably get away with this pretty cheaply (~$500).

Answer 2

Putting two Ethernet adapters in the one machine will not give you an increase in speed. You should disable the existing 100 Mbps LAN card and install a 1 Gbps Ethernet adapter card. You will also need a fast switch that offers Gigabit LAN ports. As this is a lab environment, you will either have to allocate static IP addresses to the 80 machines in the lab (plus your desktop PC), or have a DHCP service somewhere on the network.

Answer 3

Can't double your speed because you only have One Modem...



Your network adapter can take in 5x the speed of your Modem connection... Physically you would need Two WAN connections.



You would need two Modem... each connected to your PC... and yes services will alternate making it seems like your doing more...



But if your downloading say Netflix on one connections it will not use both... every packet is sequenced...1, 2, 3 etc... so must use that same adapter...



Also you would need a way to alternate the connections...

Meaning you would have to use two different browsers..



In LAN settings go to Advance and don't select "Automatic Configuration Script" and enter the IP address of that Router's default gateway... This is for Internet explorer only...



In FireFox in Network settings Advance and use "Automatic Proxy Configuration Script" and add IP address of default gateway you wish to use.

Answer 4

Agree with Jeff, with Win 7, you don't have the ability to do NIC teaming. This feature is only available on Server OS, like Windows Server 2012
