What speed does everyone get on 802.11n 2.4 Ghz?

I'm struggling to get over 25 Mbps (small b) in speedtests while my wired desktop gets the full 45 Mbps without fail every time. So I'm thinking the wifi needs some tweaking. Wifi is currently running on a non-crowded channel 11 (scan shows only 1 source close by on channel 1), 20 MHz channel width and restricted to N-2.4 GHz only, WPA2 AES encryption. To my understanding everything is correctly configured.

Reading reviews of latest and greatest routers like RT-68u and EA6900, their 2.4 Ghz 20 MHz tests also struggle to get above 30 Mbps. Is this really the case with 2.4 Ghz?

My router can't do 2 bands at the same time, so I have to choose 2.4 GHz to have compatibility on lesser devices. Only thing I can think of is to use 40 Mhz channel width, but I'm worried it might affect range of the router?
 
oh I've ran enough cables :p

I'm just wondering what's other people's wireless speed. With fibre speed of 40 to 80 Mbps, 2.4 Ghz seems to struggle to fully utilise it.
 
Going to depend completely on your wi-fi adapter and router. When I upgraded to the RT-N66U we moved from a few Mbits/sec in the bedroom to a full 60Mbits/sec via 5GHz wireless... but then I paid extra for the 2x2 wireless card in the laptop...
 
What's your 2.4 GHz speed?

How well is your 5 GHz coverage? Does it penetrate plaster walls? Funny enough I was actually considering that router or RT-AC66u, until I read that 2.4 GHz speed doesn't actually improve over my current router.
 
Not really tried 2.4GHz. 5G works well for most of our devices (certainly the ones I am concerned about with speed!). As to 5GHz, the bedroom is around 15 metres away from the RT-N66. Direct line-of-sight is through a single thickness breezeblock wall. We have a new house where the upsdtairs is totally plasterboard construction, so no brick. If the signal doesn't go through the breezeblock, it has to go through a plasterboard ceiling, wooden floor and then through 2 other plasterboard walls....

We have more of a problem with 5GHz when the line of sight is through a very acute angle of brickwork (i.e. along the edge of the house). We have one room where that is the case and sometimes the 2.4G channel is selected then. I'm not particularly worried about this though as it is my office and there is a direct wired connection in that room.
 
You could try running a Powerlink rather than cables., provided you have a spare power outlet near your computer ( Note these devices do not like multi-way adapters or multi-way trailing sockets ) . I'm running one as a "Temporary solution " at the moment , But I have connected the computer to it via Ethernet ( only 1.5m though)
 
Oh there's no problem with my desktop, or NAS or main TV, they are al wired. It's the wireless devices (mostly upstairs) that has intermediate drop outs. Youtube would occasionally go all low bitrate blocky then recover to normal HD. Speedtest shows the speed isn't constant, speed goes up and down like a yoyo.

I'm tempted to get a simultaneous dual-band router. How does switching between 5 and 2.4 Ghz work? Are they on different SSID? I've seen VM hubs broadcase different SSID. If different SSID, the fallback to 2.4 GHz would introduce a break in connection.
 
Have you considered homeplugs? I'm using them and whilst they are not as fast as cat5 they are asignificantly faster than wifi. I avoided them for years but they have come on in leaps and bounds.

Generally, they don't jump. Switch on the device and it sees one of the two networks. It will stay on that network until it can't see it - even if the other is faster... At least that is my experience...
 
Getting 25Mbps between my laptop and a Sky 2.4GHz router, wireless connection speed at 72Mbps, 20Mhz width and WPA2 encryption. In all fairness it doesn't bother me as any serious work is done using hardwire between my workstation, sinology and laptop.

Even 802.11ac isn't fantastic to be honest, what you make up for with speed you lose dramatically with range, which is a highly costly problem in enterprise deployments as it usually means one AP per room!! The MacBook Pro 13 at work is particularly bad for it, and with no Ethernet port I've condemned it to be nothing more than a training device, shame considering what it cost!
 
I get between 51 & 61 Mbps wireless using the red brand.

Had loads of grief before being upgraded to the new super hub. One thing that was pointed out to me whilst tuning, Chanel's 7,9&11 are defaults & it was recommended to try others to find the best.

Top of my head, I'm on 5 now.
 
7 and 9 are odd channels for defaults as they would definitely suffer with channel overlap, not that it matters that much except from enterprise deployment as most consumer equipment now changes dynamically so setting it statically is sometimes counterproductive depending on density. Is 51-61Mbps your actual throughput or the connection speed?
