Re: This months of work from home showed too....
Years back an IT big wig was forced\shown the door to move to a role from where he had been head of a major chains infrastructure, to the IT point of contact at one of our facilities.
He logged a ticket saying WiFi wasn't working on a laptop (In a meeting room), I decided to make a site visit to pick it up (Billable mileage & early finish late afternoon, as it happened I didn't & went back to my hub\home site).
No fault found with the wireless unsurprisingly, so the next day I ring him back.
But not before my permy network guy, now reduced to site security & the only guy who knew where everything was across many sites mentioned that he knew (Installed) the WAP was right above the door to the server room/patching closet & passing through the metal framing in (Lots of) the walls, meant that anyone with a wireless connection was going to struggle at one end of the aforementioned meeting room (Connections to projector\speakers), being as it was right on the range limits without any metal in the way & the other end didn't have a snowballs chance in hell.
Thus armed with that knowledge I informed the former big boss with 0% practical experience that there was no issue with the laptop other than its inability to connect to a signal that was weaker than 1970's British Rail tea. Dropping it off the following day further boosted my mileage expenses claim for the week, while en-route to another site, which was nice.
My current accommodations came wired to certain parts of the house & when the basement was developed, pushed for about 12 network points to be placed in various parts of the three new rooms.
I have a app on my phone now called SciFi scanner IIRC (due to its Tri-corder type of multipurpose functionality) to see what channels the neighbours are using\broadcasting on their router & pick one that isn't being used by anyone close to hand, when setting up a new router.
WiFi is nice, but you can't beat a wired connection for reliability.
