Well, there you have it. Been behaving nicely now for over a week. The little receivers are now sat mere inches away from the keyboards and mice, and that seems to do the trick. Thought I'd post back to confirm. Regards, Nige

Well, using the USB extender about a foot away from my keyboard in direct line of sight, it seems to be working great without any problems. Been using it for about a week now like this.
my receiver is only 60cm away, and it still has problems. It could be some other devices nearby, but it could also be line-of-site issues. I wonder if Logitech has any tips on the topic.....

exactly the same problem, but on a K340.
I saw mention of wireless/bluetooth interference, and as I am running on a network cable on my notebook at home, I will keep it disabled and see if it happens again. (just happened again with wireless turned off..... gonna try a different usb port, maybe on the side, instead of the back)
having to run the extender cable with the unified reciever as close as possible to the keyboard sounds like a bogus copout solution to me.

i agree, the usb extender is a completely bogus fix. the whole reason i paid extra cash for this keyboard is because i want to reduce the wires in my room and go wireless.
aside from that i choose logitech because i thought they were realiable but it seems that they don't really care because they dont even bother to post a single reply.
it seems you guys are getting bs from their support team too.
i can't believe i brought this crab, i got a cheap wireless keyboard+mouse combo from radio shack for only $30 and it works for over a year(actually is still working), but i gave it away and replaced with this because i wanted to be able to conserve energy by having a turn on/off button. but it turns out to be garbage because the keyboard is lagging like crazy and it just won't ork properly when i needed.

I've had my k350 keybaord and mx revolution mouse for a little over a month and didn't have any problems until i upgraded my pc.
After reading a number of threads and forums relating to this issue I ultimately put it down to interference as this issue never happened with my old machine.
So what changed?
It turns out that the issue is with the built-in wifi card on my motherboard. As i have a wired connection I disabled the wifi card from Device Manager and bingo... no more lag and the keyboard is working normally now.
This is my experience of the issue and how it was resolved.
Having said that it is quite lame that the issue is down to interference. It means in the future if i need to use wifi I'll have issues with the keyboard

I know it's an old topic, but I had the same problem and my problem is solved now.
For me putting the receiver inches away from my keyboard is not an option. So I just contacted Logitech and explained the problem. They asked me a couple of question that may be of some help to someone:
(for the record, I use the K350 with the Performance MX mouse)
- Do you use 1 receiver for the K350 and the Performance Mouse MX of two?
- Where did you put the receiver in? In the USB port at the front of the computer, at the back or via a USB hub?
- Are there any other electronic and/or wireless devices near the computer?
- Does the problem still occur when you change the batteries of the K350?
My answers were:
- only one receiver
- Front of the computer in the USB port
- Yes, close to the computer are: HDTV, PS3, HD cable receiver and a refrigerator.
- Haven't tried it out yet. I think I replaced the batteries 2 times at most.
Logitech concluded that my K350 is or has a defect.
They offered me a replacement for my K350. They said the K350 isn't in production anymore so I could choose a new keyboard with a maximum of €65.
Because I couldn't find a good replacement for the K350 within the €65 they said they could get an agreement for the K750 or the K800.
So there you have it! The delay problem is just a defect of the K350 and I got it replaced for the K800 :-)
Off course I was still within the warranty time. The website I bought the K350 from gave me 2 years warranty but on the Logitech website they give a factory warranty of 5 years...
Anyway I had just one month left of the 2 years warranty, scanned the receipt/warrant for my K350 and sent it to Logitech and got myself a brand new K800!
Hope this will help everybody who has the same irritating delay problem with the K350 as I had.
