PC disconnects from wi-fi

Gordon as far as I am aware all cordless phones run at either 2.4GHz or 5Ghz - if you look at the base of the device(usually the base station phone) it should give you the specs. The 2.4GHz is a very commonly used frequency and while fairly good usually up to and maybe over 100 metres is also better at penetrating through walls for example. Just so you realise that your wifi is available to even your neighbours and if they should ever get hold of any passwords to your system then they can tap into it and even use your broadband if that is also wifi. You may know this from for example staying at hotels etc where you get a code for using the (usually) free wifi they have at the establishment.

Plus remember also that I mentioned that cordless phones are not the only devices using that frequency ie remotes, microwave ovens etc only remotes that use an infrared beam/frequency are different and that would not affect your computer wifi.

I stand to be corrected of course on anything I have said the only wifi devices that I am aware of that operate on different frequencies are walkie talkie devices and ham radio etc.

Personally I prefer Ethernet where possible because it is far easier to use and generally much faster than wifi.

I have a rather ancient AT&T cordless, runs at 900mhz. Just adding that in case. One of the original freq. bands for cordless.

Well tomcat you prompted me to go looking and I found this Cordless telephone - Wikipedia just amazing I thought those old frequencies were long gone unless I suppose like you one has one of the older models.

Plus I stand corrected in that instance and I see I have been quoting 5.0GHZ and it should have been 5.8

Wireless phones, which may be 2.4 or 5 GHz, as mentioned, can interfere. I had a situation where every time mine rang it disconnected the network, but it came back on its own.

Of course, microwave ovens can have an effect. Maybe even a neighbor has some device..

Yep saltgrass mate basically what I said in post #11 and I should have added that it might not just be your devices it could be one or two of your neighbours or you might live near transmission towers there are a lot of variables.
