i bought a logitech cordles K350 keyboard ... it worked fine the first few days but now it takes like 2-3 seconds for each letter that i type to appear on screen ... removing the receiver dongle and power cycling the keyboard sometimes help for some minutes but then its ackward again. is that a known issue? i am using the usb2.0 ports of an ASROCK P67 extreme V6 motherboard and windows 7 64bit ...
thank you for your time

ah ... it seems as if it was a transmission problem. how stupid of me to think that a wireless keyboard would be able to work when the receiver is not placed right next to the keyboard but behind a flatscreen in a distance of 40cm from the keyboard ... i wish they had the wired version in store. durr ...

Thank you for posting your issue to the Logitech Community Forums.
It is great that you have seemed to have your keyboard working. However, in a matter of signal degradation, there could be other factors besides the distance between the keyboard and receiver. These factors are:
Hope this helps!

I had the same problem with my K350...worked great the first few weeks, then suddenly had a delay, and now not even picking up all the letters I type. I switched back to a plug-in keyboard, and had no problems. Then switched to a friend's WAVE cordless keyboard, and after a week, started having the same problem. I removed all other wireless items from my office, but that did not help. My USB plug is in my computer at the position closest to me. I am sad because I love the feel of the keyboard, and the fact that I do not have to work round the cords, but since I am a typist and get paid by the line, this will not work for me. I type nearly 200 wpm and I need it to be able to keep up.

Having exactly the same problem. K350 works fine intermittently, then suddenly experiences massive lag. Keystrokes missed, huge delay in characters appearing... basically the exact same issues as the OP.
Replaced the batteries in the keyboard, no help. Moved the unifying receiver from port to port, which fixes it for a while, then the same issue rears it's ugly head. (The keyboard is never more than 2 feet from the dongle)
Absolutely MADDENING issue, and if it wasn't for the fact that I love my Performance MX mouse (which occasionally sticks as well, but a recharge ALWAYS takes care of that) I'd throw this piece of @#$@# out the window and buy a different brand.

I have found that if you go into your power settings, and then the advanced menu and disable selective suspend under the USB drop menu this can greatly improve performance.

I too have been experiencing this issue but, it didn't happen immediately it was within a couple weeks of purchasing the keyboard. I work in public safety and do a lot of typing. With my big hand s I love the way the keyboard and mouse feel but, it is not a very functional system.
For what it is worth I have access to a Faraday Cage and I took a computer in there with this keyboard setup. This eliminates or makes outside radio signals negligible and is used to protect equipment during EMPs or for radio testing.
This setup did not work any better in there than it does on my desk. There is an issue within the drivers I suspect.
Win 7 Pro 32bit
Intel i5-2500 3.3GHz
4.00 GB with 3.24GB useable
Windows Experience Rating of 4.9
I've tried plugging the "unifying receiver" directly into front USB ports, Rear USB ports (Computer module is within 18" of keyboard and 36" of mouse) I've also used an extension cable and placed the receiver in various places in front of the keyboard, mouse, and even underneath them.
For what it is worth, the mouse rarely ever has a problem, sometimes it will hang for a second. Usually though the issue is with the keyboard. It acts like it is going to sleep on me. Maybe that is why the batteries can last over a year??? It really is annoying and I will soon be switching back to a regular wired keyboard if this problem can not be remedied ASAP!

Please check out the following FAQs:
You probably have tried some of the steps on these FAQs, however is important to rule out probable causes.

I had an oldish Logitech wireless worked well for ages but started playing up recently - lagging/freezing issue. Bought a new one a couple of weeks ago - same issue. Took it back for a replacement - same issue. New batteries - same issue.
It appears that taking off the back battery cover and turning batteries "resets" it and off we go again for awhile. What the???
Batteries are new, cannot see any other main power/wireless/ garage door etc excuses that are relevant.
Very peeved at issue and extremely frustrated!
