I've given up on trying to decipher the geek-speak all over the net when this question is asked. My setup:

Openelec
D-Link 2750U router
Numerous wireless connected machines

My transfer speeds from my Windows machine to the Openelec box (or vice versa) are max 5Mbps, and this is indicative of the other machines which are no quicker (Macbook, tablets, phones etc). My connection speed is 72Mbps (set to auto on the router) and at 40MHz in both bands. Whenever I change the rate the transfer speed appears to drop down to between 2 to 3Mbps. Changing to 20MHz in both bands doesn't help apart from changing the values of the connection rates I can change. Changing to mixed mode means none of my machines can connect to the router.

So what is going on here? My Netgear DGN2000 also shows transfer speeds of 3Mbps. BTW it isn't a problem with structural interference as I have one of the laptops right next to the router now and there is no change.

My Windows machine has an Intel N-130 wireless adapter. Any help would be appreciated...
 
Its likely a combination of factors. Since windows 7, speeds have been lower on network transfers...even on wired. Never worked out why, but I've never been able to hit near theoretical max with the new network stack.

That likely isn't the cause. Its more likely that you've got a device connect that only support <n. Routers generally can't do n and b/g at the same time so if there is one slow device then everything drops.

I've been in a similar situation...and never found a solution tbh. :/ Mainly because on some n devices you can't force it. If someone does have a solution then I'd be interested too. Specifically one that doesn't involve replacing gear.
 
Does that mean that any wireless device connected at the same time or any device that has ever connected to the router?

Because if I test it with just the Windows machine connected, I get the exact same results, and my Windows machine is Wireless-N capable. I checked on Intel's site and ensured that my adapter settings match what they state to use N-speeds properly...
 
You'd have to reboot the router.

As I said though...I haven't found a solution. I've got nothing but n devices connected & its currently connecting at 30mbps...

And I can't force n on either the router side or the device side. Its a bit of a crap design imo...allows you to force older standards but not new ones. FTL.

Quick bit of search says WMM must be switched on. Saw a bit of 90mbps...which is n standard, but only for a sec.

tbh DJ I'd just wire it with gigabit cables if you need reliable high throughput.
 
Wiring it all up is simply not an option. They're not all stationary machines and there are quite a few of them disparately placed around my property. I'm not digging up my garden and running wires throughout my entire roof to avoid using wireless. To be honest it works fine for now, but I just feel that it should be a lot faster than it currently is. WMM is on.

But let's assume that this is the best it's gonna get, is 5Mbps transfer speed (based on a 72Mbps connection) normal, or should it not be higher than that?

I think its normal.

I've NEVER been able to max out transfer rates over any of my wireless networks (@home), theoretical speed of 50Mbps usually gives me a transfer rate of around 2-3mbps.

Never really bothered to look into it with too much detail though.
 
DJ you sure you don't have your units mixed up?

5mB/s on a 72mbps link is plausible. Bit heavy overhead, but about right.

5mbps is dead slow for a LAN/WAN...like ADSL dead slow.

tbh I'm pretty sure you've got the unit wrong. You'd be screaming bloody murder if it were 5mbps.

So yeah its probably about right (assume mB/s).

If you need a specific link to be faster then you can try throwing some 5ghz gear in there...that would isolate it from the standard 2.4ghz stuff. Its a pretty nasty solution though...

Also...try to keep the vendors the same...Dlink router...Dlink dongle.
 
Okay the transfer speed is MB/s not mb/s. Drops to around 3MB/s when it has to go through a few walls but definitely MB/s.

I still don't understand why it is connecting at 72Mbps (58Mbps now) when both router and laptop are capable of far better connection rates. I have set it to auto on the router now as the fiddling doesn't help by the looks of things...
 
I dunno dude. I think getting the promised 150 / 300 mbps might involve candles, chanting and a human sacrifice.

You can use netstumbler to work out what other networks are interfering, but I don't think thats the issue here.

soz don't have a solution for you. & Would be mighty impressed if anyone else does.

@DJ... why don't you try Ethernet Over Powerline adapters? I'm using them throughout my house and they give me a very reliable 10MBps+.

Have a look at this thread: http://mybroadband.co.za/vb/showthr...dapters-good?p=9998938&highlight=#post9998938

There are only two additional sites I'd need them - bedroom and bar, and the throughput is actually fine - there is no buffering noticeable on any machine. I was simple curious as to whether I'm actually getting the correct throughput as per my hardware. Seems I am. One wonders then how on earth anyone could ever achieve the advertised speeds, or even remotely close to them?
 
Arnt modern N routers rated at 300mbps = 75MB/s?

The best ive gotten with the laptop right near the router is 2-3MB/s (direct file transfer)...not even close to 75MB/s

Either they are lying or we are doing something wrong.
 
Wireless has an element of black magic to it and it sucks from personal experience.

So my 5-6MBps is actually pretty good...?
 
If you speed in Windows is listed as 72Mb then something is wrong or you have very bad signal.

It's should be 150, 300 or 450 at full capacity.

72 Megabits (Mbps) / 8 = 9 Megabytes (MB/s)

Add some overhead and 7MB is exactly what you should be getting with your current connection to the access point.
