To prevent g device slowdown the router needs a more complicated antenna design. I believe a lot of routers have mimo antenna design such as the AirPort Extreme and wouldn't be affected by the g device slowdown. Likewise many ISP supplied routers are also good presumably to stop disgruntled customers

Somebody step in if I'm wrong but I personally don't see this slowdown at all.

I don't think that is right at all. My Billion 7800n has MIMO (as I believe all wireless-n routers with more than one antenna do). I also have a rather ancient Netgear DG834N which also supports MIMO and is also affected by the G slowdown.

Just to make a point I believe a lot of routers are no longer affected by this g device slowdown. A lot of the cheaper routers and early spec N ones are.

Why do you believe this? Can you name a specific make and model of router which isn't affected by this problem?

Certainly I do not experience it with a sky hub. Having a g device connected makes no different to the throughout I am getting at wireless N of around 50Mbps.

Your wireless N speeds should be a lot faster than 50Mbps. The Wireless G ceiling is 54Mbps.

Wireless N here connects at 300Mbps, and internet throughput is at the maximum (70Mbps). As soon as a G device is connected, the N speeds drop to around 50Mbps.

My sky hub has a wifi transmit rate of 144Mbps.

I get 50Mbps on speedtest using 2.4Ghz and a sky hub with a wireless N device connected

Also with 20 wireless devices connected, of which 4 are wireless G I STILL get the same 50Mbps speedtest as having just one N device connected.

I don't get 70Mbps as firstly it's not 40Mhz the sky router but also probably due to high 2.4Ghz utilisation around here.

So for me absolutely no difference.

I do have a 5ghz router hooked upto the sky hub which gives me 70Mbps or above.

As for standard wireless N router, the sky hub. Mines the same regardless. 50Mbps both times.

Same with my BT homehub 4. Exactly the same results as above.

The only thing that slows things down is when a b device connects in my experience.

You deleted your post but it's still in my email

You said

"If I force my router into wifi-G mode, all of my devices connect at around 50Mbps too. Connnection speed only degrades over distance."

Yes I agree.

I am not disagreeing with you.

What I am saying is that my N devices connect at 144Mbps, G devices connect at 54Mbps.
On speedtest.net I get 50Mbps on N devices EVEN WITH g devices connected.

I am NOT saying that my N devices connect to the router at 50Mbps. They connect at 144Mbps even with g devices connected. The N devices get a speedtest at www.speedtest.net of around 50Mbps

Ie in the real world when downloading I see no difference.

Couldn't the OP just get a simultaneous Dual Band Router?

This would work provided all of the N devices were 5Ghz, this is working along the assumption that g devices slowdown the N devices massively which I honestly do not see personally.

I think the issue is just the router they're using.

I deleted it because I didn't like my own tone when I re-read the post. I'm sorry.

I am absolutely seeing a real world difference when downloading once a G device is connected.

The N devices download from Steam at 70Mbps, but as soon as I connect a G device elsewhere, that download speed drops to around 50Mbps. That is significant when you're downloading a 20GB or 30GB game... which happens quite a lot here due to Steam's regular discounting.

I think the issue is just the router they're using.

Then I'm surprised because the Billion 7800n has an excellent reputation.
