That's disappointing! I'm going to give mine a go and if it's no better than my 56U it will be going back. I thought you could only lay this one flat anyway? Surprised the signal isn't any better. Are you using an AC card with it?
I don't have any AC clients, just n. All the essential hardware is connected via ethernet.
Yes it can only be laid flat but for some reason I assumed it would have come with a stand like on my 66U. I've looked on Youtube and people have connected fans to theirs or laid it ontop of one of those laptop coolers.
I did hope that wireless would be stronger but I checked link speed, attenuation on all the tablets at various distances as well as running speed test and they weren't better than my previous router.
The 68U is often described as a router that has aged graciously so I asked them to apply the same discount to that which they did so I am getting that. I did consider the AC3200 at £150'ish but it's just not worth spending that much on a router for my setup as I have an access point.
The 87U is being picked up tomorrow.
The 68U from what I understand has had a subtle revision also. In the States it is called the 68P but for the EU it's 68U B1 and C1 (C1 being the best)
A1/A2 is the old CPU BCM4708 at 800mhz. A2 added sheilding for usb3.0 interference
B1 (BCM4709 1GHZ) and new skyworks amp for 5GHz
C1 should add to this with new 5GHz and 2.4GHz chips should be 2 BCM43602 which will have there own CPU to offload wifi processing from the CPU, but nobody is sure yet.
