I've called on such and frankly you should already have a LAN so the number one cause of what you wrote is usually an old WiFi router or WAP. It seems odd to look into creating yet another LAN when we haven't heard what you tried so far.
Again, no service I know provides a WAN (as in the Internet) without a router. And that router would give you a LAN.
Also, without a device count and site survey no one can guess what a new network router and setup would look like.
My office is in a large office building with many businesses. All the offices connect to the same network in the building. In our office we have about 7 laptops and a wi-fi printer. A couple people have problems printing - it seems to intermittently drop for them and takes a while or a reboot before they can connect again. Also, if they send more than one print job at once it usually only prints the first job, the rest have to be deleted from the spooler and sent again one at a time.
We suspect the issue is network related and how our print jobs have to go thru the WAN to get to the printer. We'd like to set up a LAN in our office where all our devices connect to that network and the WAN is just for getting out to the internet.
We're a small medical company w/out a dedicated IT person, but we're somewhat savvy. Any advice/suggestions on a type of router to get? Will we need something like Active Directory for logins? Any pitfalls to watch out for? Any feedback will be appreciated.
Thanks in advance!
