Top right corner, the app gives you the name of your adapter.

You will not get N speeds with a G adapter. In order to get N speeds, you have to have all N components.

Oh yes!

But mate my ipad and my ipod 4G they are both N compatible and if i perform and speed test i only get 20mbit. (my internet connection using an ethernet cable gives me 45mbit).

Running inSSIDer on a PC that only has a wireless G adapter doesn't strike me as a valid test. The best that adapter can ever do is G speeds of 54 MBps. Even if your router is N it won't display it. Here is my screen done on my XP PC with a D-Link DWA-552 extreme N PCI adapter. My Router is a D-Link DIR-655 extreme N.

My SSID is DAS Link and my router is set to auto 20/40MHz for band width and auto channel scan. Auto channel scan is supposed to let the router select the best channel(s) based on other wifi networks in range. My router and adapter won't do 5 GHz. I'd be very surprised it your G adapter will do the 5 Ghz band, you might want to check the specs. I've noticed that the longer I leave inSSIDer running the more networks that show up. I've seen up to 20 listed at times. My router is in my basement and the XP PC is 1 floor up. I've read that having even one G device on an N network will cause the N network to fall back to G speeds. I've never bothered to try and prove it one way or the other though.

You are right. Per spec, if an N router has a G device connected to it (and does not have dual band capabilities [be able to have independent G and N frequencies for both types of devices], it will step down)

First of all thanks for your interest alphanumeric, this is a laptop with N speeds:



I've read that having even one G device on an N network will cause the N network to fall back to G speeds.

mmm interesting.

Nop i didn't miss what you said. Thanks now i know that i need to buy a dual router.

update: check this out mate a brand new screen take with only the laptop N, no G devices connected this time (router name changed and rebooted first of course).



It still gives me 54mb.

Because your N adapter can fall back to use older routers. You need to eliminate G from your router's broadcast (switch to N only).

Looking at your screen shoot your router is only using one channel and inSSIDer is showing it as a G network. I'd say something isn't set up correctly in the router. If you look at my screen shoot you'll see that all the 300 N networks, including mine, are using two channels. My router is set to G and N, my daughters netbook only has a G network card. Mine isn't dual band, maybe yours is N on 5 GHz but only G on the 2.4 GHz band?

Thanks

But there's nothing i can do about it, my router ISP doesn't have that kind of option:

Exactly, something is not right, what about my ISP having hacked my router's firmware?????, i mean wired i get 40mbits (that's what i paid for), but wireless only 20mbits... It appears to be an N router but it doesn't behave like that but like a G router..

No 5ghz here, the ipad is 5ghz compatible but i'm still with 20mb in 2.4ghz..

I'd say you need to look for a bandwidth setting, probably some where under advanced. If its set 20 MHz it will only use one channel. Set to Auto or 40MHz it should use two channels. Keep in mind that different hardware/firmware do different things. How my router works with certain settings may be different from what happens on yours because the firmware is different and reacts differently under certain conditions. You may want to turn off any wireless G clients you have and only do your testing from a wireless N capable PC. That way you can rule out a G device causing your network to revet to G instead of N. Once you actually have inSSIDer showing your network as 300 N you can fire up a wireless G client and see what happens.
