Duo connection possible? Wifi + Lan

I am in college dorm and the internet here sucks. However, there are multiple ports per room and multiple wireless router connections in the building.

I was wondering If i could connect my laptop to a wifi connection and a separate lan connection and to be able to utilize both connection to improve my internet speed.

 

Nope, there isn't a way to do it.

 

The botle neck is always the traffic speed between the router and the ISP, whether you connect with the router through a wireless or an ethernet port. So to improve your internet you must increase the router - ISP link capacity throughput.

Perhaps we don't understand well what you are trying to do, give us more details.

 

sounds like he's trying to do what some used to do with the two 56k modems back then, an SLI-type of thing. i know a computer can be connected to two different networks at once to access two different networks, and you can split resources that way, but don't know about two connections to one network

 

Yeah, that's what I started thinking, a kind of having packets of the source (pinging a web site) going to the same destination but coming from two different links, wireless and ethernet. In this case, assuming you have a driver dealing with this process, you would increase once again the speed from your client computer to the router but again the bottle neck would be the router to ISP connection so why to bother doing this????

 

well latency isn't a problem for me, but the amount of data transmitted...so I assume two connections would improve that

 

But how will you reconcile the packets?

 

reconcile?? I dunno...but it looks there there isn't a way to utilize two separate connections at the same time...thx for the help

 

If it is the same network, there basically is no way. The OS, hardware, and software are all limitations for this.

This is done a LOT with high traffic servers, but that's about it. But if the connection sucks now, its definitely a hardware bottleneck that won't change with two connections.

 

I can have my ethernet and WiFi both active. But only one will be connected to the ISP, it looks like ethernet has the priority.

However it would seems that it is possible to run WiFi and ethernet side by side using the virtualization feature, check the attached link.

I might try it, but I have read in other forums that using both cards (WiFi and ethernet) might increease the heat on your laptop and cause issues and even disconnect you from the network.

 

Hey that actually looks pretty good! but darn its in ubuntu >.<

 

From what I understand is that you want to use two independent internet connections.

You cannot combine the two connections into one big internet connection because TCP/IP just doesn't work that way. Well, technically you can, but both the receiving and sending end need to be set up to do this. What you can do is what is called Load balancing. Basically, your outgoing connections will use one internet connection until it is saturated and then start using the other one.

XP nor vista officially support this feature, but there is a registry hack that shows up when I googled Load balancing.

Try it and let us know.

 

It doesn't matter the OS, the only limit is your CPU, it must support virtualization.

 

There are some SMB class routers that support dual feeds. The load balance can take place at the router. The one that comes to mine is the Netgear FVS538 VPN router.

 

I tried it, no noticeable improvement. thx tho

 

How did you test your connection?

 

Yes, what did you try??????

 

I tried the load balance registry tweak posted by surfasb
http://www.geekswhoknows.com/articles/load-balance-two-internet-connections.htm

it basically added randomadapter and single response to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters
and that didn't work so well

however from another website,
http://www.windowsitlibrary.com/Content/435/09/6.html
suggested adding it to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
I tried that and it's been pretty good tonight

 

I simulated what you wanted to do, I actually connected my laptop to the router wirelessly and ethernetely (I hope I can say this ),and I had both connections running, local and internet. But the question remains, how does the Data Link layer decide to treat a request for Internet from the Application layer? I didn't notice any appreciable improvement.

So, you said that you tried the website above and got good results, can you please quantify it, thanks.

 

Oh I test by playing WoW lol...

Good = low latency and no disconnects
bad = latency and constant disconnects

it may just be my isp auto fixing it self but my wow condition has been bad for a year now.

the website says that you need to have two separate isp connections, and that you won't notice improvement unless you do multipliable download/upload, I suppose a way to quantify improvement is do a single download/uploads' speed/time and then double download/uploads' speed/time and do a comparison.

I know even tho i am using the same isp, but i assume my school assign each port with a bandwidth limit and through a switch connection to multiple t3, oc3, oc12 connections. So i assume two ports = 2x bandwidth

 

I would think the same, but let's say you called a web site, do the request from both cards go to the ISP? And when the ISP responds, which one is displayed, the first one to arrive?

 

i think if your loading only one website one session at a time it will only utilize one connection.

But if you are loading multiple websites in on session, i suppose it's suppose to distribute the workload between two connections...

 

How can you request several web sites simultaneously? Are you both handed like me?

 

i dunno u could uhhhh load speed test in two different browsers at the same time.....

 

Lol,

I could see an advantage using the anlogy of dual-channel memory which feed the processor via two funnels, we could see the web site request packet devided in two groups, half going through ethernet and the other half through WiFI, then sent together to the router and the ISP subsequetely. The inverse would be done when getting the web site back, but this requires processing so there it would go our benefit.

 

It is very possible to make multiple requests to to multiple webservers and download more than one website at a time.

 

Yes but here we are talking about the same web site, just one web site donwloaded faster cuz two links (ethernet and WiFi).

Did you read my post about the dual channel memory?
