Dual band wireless routers- share files across bands?
Lockedby jshoe85 · about 13 years, 4 months ago
If I buy the Linksys E3000 (simultaneous dual band) or something like it and have one PC on the 2.4ghz band and another on the 5ghz band can I share files between the 2 PC’s even though they are on different bands and have different SSID’s? How does this work? Thanks

Unless it has some smarter functionality (like VLAN, dual-band load sharing etc) active, it would simply be like a router, with two access points attached, where you still get “full ethernet connectivity”.

You would however have to enter the Devices Setup and make sure that the different Ways to connect to it are bridged.
Before buying I would look at the Instruction Manual for the device and see what it says in the Setup Side of things.
You can get the Instruction Manual from the Device Makers Web Site. 😉

I did look but I still can’t find a definite answer.

In reply to Router
I had a look at the User Guide (http://homedownloads.cisco.com/downloads/userguide/1224655340631/Linksys_E3000_UG_USA_V10_NC-WEB.pdf) and from the information it is obvious that the router will happily transfer internal traffic forth and back between the two wireless networks.
How I can be so sure?
The unit has only one single setup for the internal IP network. All wifi clients will share one common ip subnet. I.e. as per specification, they should be able to talk directly to each other.
Further, I couldn’t even find any possibility to split the two radio network into separate (routing) domains. (Guess that could be an interesting task for further development by vendor or very advanced users.) -

I’ll have to look at the manual again. Just because they don’t mention it doesn’t mean it’s not possible. What I’d really like to do is speak to someone who has the router. I actually contacted Cisco two times and got two completley different answers.

This is more a question of IP than it is a question of wireless networks. I believe wireless is a layer 2 protocol, so as stated previously by Tobi and Smeg, if both nodes are in the same IP network, and you’re not employing any particular functionality like wireless isolation or VLAN, etc. they will communicate.

The WLAN side of the router is a mac-layer bridge

As far as I know, most SOHO WLAN routers that support multiple SSIDs just dump them all into one network, as having multiple SSIDs allows you to run multiple authentication schemes all at once (e.g. WPA2, WEP, none) all based on SSID.
It’s a handy way to connect devices that support different authentication methods.
For example, a Nintendo DS game console only supports WEP, but a Apple iPhone does WPA2, so both devices can connect by defining one SSID as the one for WEP and a different SSID to do WPA2.
Otherwise you would be forced to use WEP on the iPhone.
On many enterprise-class WLAN access points, you can allow multiple authentication types per SSID, but that can be very tricky to setup. By default, different SSIDs on these devices each go into a separate ethernet VLAN, but I digress…

Linksys is trying to sell this router saying having trafficon both bands will lower congestion compared to one band… How can this be true if both networks talk via the RJ 45 jacks to wired PC’s. It’s really not doing much having 2 bands. Unless your only using the wireless to wireless communication on the same band. You know what I mean?

In reply to Traffic
A typical G channel can theoretically carry 54 mbps. An N channel can carry more.
But these (advertised) speeds have to be shared between all participants. If your neighbor is using the same channels that you have, then the routers will agree on a “time share” basis.
If your neighbor uses an adjacent channel to yours, then reciprocal radio interference may force a fall-back to “A” channels or degrade your connection to almost nothing.
Other radio interference may also lead to lower capacity.
Even if we forget about radio interference from the outside: If you can put half of your computers on one frequency band, and half on another, then there will be less nodes that will share the available communication link on each frequency = higher speed.

You can share files

I have a Linksys WRT600N which is an older dual band, simultaneous router similar to the E3000. And have connected to both bands at the same time and it’s the same as connecting another RJ45 connector to the router. In other words both bands connect to the same network so you can share files.

The wireless network side of the router is a mac-layer bridge.
This means it’s all one network, so any protocols that can talk to each other will talk to each other.

That’s what I thought…. I just wanted to phrase it so anyone who has had the router understood since there are many levels of experience here. Thanks

By default they’ll be part of the same logical network. For personal use I use a Linksys WRT610N to do the same.
