computers randomly disappear over wired network
Hi Guys
Have a networking problem that seems to have gradually made its way to the point of utter annoyance. Our small business of 7 computers and growing is networked via wired Ethernet, our ISP is a cable based provider (Shaw). For several months now since the introduction of two pre made HP windows 10 desktop machines our network has started to act erratically. Computers are disappearing when viewing them under networking. They spontaneously reappear throughout the day. Our full network map is different from each computer. The strange thing is that the computers are there. I saved shortcuts to each shared folder and placed them on each computer and they are accessible consistently, but the computers pop in an d out of existence when viewing them under the network view and aren’t accessible that way. There is no interruption or slow down in access to the internet. This problem only affects local networking.
Please see the attached picture of our network. This big "?" you see in the picture comes and goes and varies when you view the network from the other computers.
Our machines are all windows7 home premium, a mix of 32 and 64 bit and now window10 home 64bit. 3 have Kaspersky virus protection (purchased) , the others have Avira free and MacAfee (preinstalled only on the two HP windows 10 machines). The problem does not seem to be specific with any of the machines running a certain virus protection. We are not using windows Homegroup. Our advance sharing/network discovery is enabled on all the computers share the same settings throughout; see here.
Months before I have noticed the the network taking a long time to show files on one computer or the other but just brushed that off. So I don’t think this is entirely related to the two new windows 10 pcs. Our network and firewall setting shave been untouched for years now. So what could be causing this?
You can view all our hardware in the above mentioned pictures or Listed below:
Modem: Motorolla 5B 5100
Router: Dlink DIR 826L
Switches: Netgear FS 116 ProSafe 16 port 10/100
Any help would be appreciated, I’ve never had this problem before.
