Hey guys,
I've been having big problems with Wireless Logitech keyboards of late. I had an older (but top of the line with LCD screen etc.) wireless keyboard which would constantly disconnect. It had a few broken keys so I thought I'd solve the problem by buying a new k520r Logitech. However this has the same problems, random disconnects etc. which is really annoying while typing or copying and pasting etc. Each disconnection may last between 1-10 seconds and sometimes the key presses I made while it was disconnected all come through at once.

I've tried changing the batteries and different US ports. Any ideas? It also has a wireless mouse which uses the same dongle (came in combo) and works fine.

Using Windows 8.1 with Intel H67 CHipset and mouse plugged into USB ports. Keyboard and dongle are 50cm apart.

Most of these keyboards all use 2.4Ghz so interference from common sources such as microwaves, WiFi etc can all cause problems.

Hmm OK. Weird that the mouse works. Running standard Mikrotik router and pretty sure the Uniden DECT phones are on 1.9GHZ - first time ever had a problem with interference lol!

You didn't need to create this topic in two different forums.

Metal desks can prevent wireless devices working properly.

Try it on another PC.

It MIGHT be....

kb going to sleep (to save batt power)
USB port going to sleep

Ah what other forum was it posted in? The Geekzone site wasn't loading properly for me last night when I was posting the thread.

That's fair. It was in another of the subforums here on GZ, I reported it for removal, which has likely been done.

Get a USB extension cable and move the dongle away from all your other USB ports. Particually if one of them is a USB3 port.

I had similar problems with a Logitech MK250.
I suspected the problem was because the receiver was hidden on the back of the pc, so connected it to a USB extension cable and positioned it well above the pc. Problem solved.

Hey guys,
Yea plugged into a USB extension and voila! No problems since. Good advice as always :)!

Seem crazy Logitech are continueing to sell this product, I bet they get heaps of support calls about it. It really degrades their brand image in my eyes - if there is a faulty product fine, recall it but to sell it for so long?!
