Been trying to figure out how one of my desktops PC connected to two ISPs — Smart Bro and PLDT myDSL. The myDSL is connected to a router and hooked up with the other PCs while Smart Bro is hooked up directly into this one desktop. Now, if we wanted to play Warcaft 3 on the network, only my laptop and the other PC can join so I am thinking that by adding a second LAN card and hooking it up to the router, this PC will also be part of the network.
Is that possible? I haven’t tried it though. If both can’t work at the same time, maybe I’ll just disable one while using the other.
Any better arrangement for this?

Yes that’s possible. I just don’t know the pros and cons. Haven’t tried it as well.
I’ve seen some computer cafes that have their individual PCs having two LAN cards installed and working. I was curious and asked some of their people and they said that it helps the network speeds to go up and it also acts as a secondary network.
I didn’t aksed more details from then on though.
well i doubt it will work kasi pag nakadial-up ka then naka on yung lan mo it wont browse pero once i disable the lan ok na… hmm… so theoritically para the same situation… the only thing you can prove if it will work is to try it madalai lang naman mag kabot ng lan card sa pc.. I have to 2 lan cards on my pc though 1 ISP lang which is smart bro… OH WAIT!! may naalala ako you can bridge 2 lan cards as one google niyo meron nito pero pagkakaalam ko dapat the same ISP and The Same Package or bandwidth…. yes i think thats what you want….
kung di nagpost yung first reply ko:
hmm bridge the lan cards as one pero I think you should have same ISP and Bandwidth to do so, try googling for this technique alam ko meron nyan eh…
a pc can have 2 lan cards pero 1 ISP ang alam ko, yung pangalawang lan card is for networking your other pc and share the ISP…….
Yup, it is possible to have 2 LAN cards in one PC and then both will function well at the same time. The router will automatically assign an IP addy to the PCs connected to it and just configure your network through the Set up a home or small office network wizard (the wizard, actually, really works! =)) then each PC will belong to one network. oh, and if you do have a firewall (which i am assuming coz you have a broadband internet connection), just make sure to enter the IP addys of the PCs to the trusted zone of the firewall to have a direct connection to each PC
hello i have two lan cards installed in my pc. through 1 pc i want to connect 1 lan card for broadband net and through the other pc i want to connect another pc (one lan card on it )
for sharing my files and folder and internet.please give me the detail step for it.
hello
i am using internet with LAN and i installed 2 LAN cards in my pc plz tell me if i connect both lan cards then can both cards can use inter net at one pc ????i mean if i connect my pc with 2 lan cards then can i double the speed or not ???
@shahzad
installing 2 lancard while accesing 1 ISP is not advisable.It will never double the speed of your connection neither.
@shahzad
Are you trying say that you want to acces the other pc by 2 lancard without a router? in order to join and/or create a network and share files and net connection? Well, its possible.
hai
this is so funny its never happen ……..are u making to fool to otheres …….when u install two lan cards in one pc nothing is happening there …….hhhhhh this so funny dears
if any body can increase just contact me thorugh my email id ,,,,,this is my email id lightwave1232001@yahoo.com,,,,,,i wanna accept the replys come on
thanks
MOD: Delete first post plz…
Two Ethernet cards you say (or more)?
AKA: Teaming or EtherChanneling (cisco’s name for it)
There are a few reasons why you would want two Ethernet cards on a system.
+ Load Balancing / Enhanced Transfer:
If you are dealing with two 100MB/sec card you would benefit by being able to transfer 200MB/sec between the computer and the router. This will not make your connection from your router to the internet any faster, but does increase the speed at which your router can send the internet bandwidth to your computer. If you have two computers setup with two Ethernet cards/ports each you would be transferring at 200MB/sec between them.
+ Daisy Chaining LAN & Internet:
Router or Cable Modem === Computer 1 === Computer 2
It is possible to use both Ethernet slots on ‘Computer 1’ to share the connection with another computer. ‘Computer 1’will act as a router in essence. Network professionals know it as ‘Daisy Chain Topology’.
I don’t know about this next one (maybe someone can help)
+ LAN based printer connectivity
Computer 2 === Router === Computer 1 === LAN Printer
This is not a good diagram to describe why you would need it so let me explain. If you had a 4-port router and you had 4-systems already hooked up, could you add an addition card (or use an available Ethernet port) to bring a LAN Printer onto the network?
Any help…?
It doesn’t matter how smart someone it, as everyone has questions…
I have the same network configuration with you. What i did before the IP of each devices (router and PC)was in the same subnet in which you can see each other. But if you change router’s subnet, only those PCs with same subnet will able to see each other but you (computer1) can remote administer (using ssh)the other (computer2) and can also able to connect LAN printer as long as it in crossover by adding additional 1 NIC in computer2.
You can correct me, if i’m wrong…
I got your idea on load balancing/enhanced transfer, right now in our connection we have 2 WAN connection through ethernet but the problem we run 2 proxy servers. To save energy and resource i plan to have 1 proxy server with 3 NIC (2 for WAN and 1 for LAN). I try it locally, on my 1PC with 2NIC, 1 is connected directly to router and one is connected to switch in which it is connected to the router. It will give problems when you put 2 gateways…
Router === PC 1 === switch == PCs
++ ++
=== = = = = = = = = =
Does it possible to implement in the Proxy Server?
someone told me you can’t use both lan cards at the same time. you gain access to 1st network but not the other (vice versa)
for load balancing between two WANs you might want to try linksys’ RV series. i use RV042 sa bahay with a pldt dsl and a smart bro as my WAN connectivity. nag loloadbalance siya in a round robin fashion meaning, if you access site 1, it will go through dsl, and if you access site 2, it will go thru smart bro. you could also configure it so that say a specific pc with a specific ip in the network to go through only dsl.
WAN1=PLDTDSL—RV042—PC1
WAN2=SMRTBRO–/ \–PC2
It will work… but dont push your luck for more speed cos it will not gain any. Ako ata yung dinidescribe above na shop na may 2 lan cards per comp.
I have 1 router pang dsl and a switch for networking.
Lahat ng first lan cards is connected to the router for internet connection then lahat ng 2nd lan cards connected sa switch. the reason for this is to stop crowding the router which is used for internet connection with connections na lan games lang ang ginagawa. kaya lahat lng ng naglalaro sa switch lahat ng traffic then lahat ng iinternet sa router.
Ngayon hindi na naglalag yung network games kpg may nanonood ng youtube.
pfsense. all in one. load balancing, bandwidth management, squid cache much more than cisco or other router can do.
1PC or virtual machine, 1 NIC(gigabitNIC much better), 1 switch. actually most of all above works but i got work in a very cheap way.
current setup.
1PC dedecated (were pfsense installed) for movies, torrent download and squid HEAD. pfsense router for load balancing (PLDT & SMART), bandwidth management.
