... long story that I already wrote once but as this online forum logged me out - probably due to time - it has been lost.

My point: long time, a lot of patience and trying other devices (in my case a change from my Lenovo x270 to my Samsung Galaxy Note 4) made it possible to set the extender up.

PS Instruction video, content in the manual etc. didn't help at all and PPS I am used to set up any type of digital gear.

Yes, I have connection and it is running as supposed. Actually pretty well. The only thing I would like to see improved it so have it hanging outdoors in teh weather of Scandinavia. That will take a more tight box, but it should be easy to make and it will really be an improvement.

But for the manual and procedures: a) My first scans didn't show any network. b) during these at some point I actually did get connection through the extender to the router and internet. My Pc still couldn't see the connection but it was there. c) Then I had dinner so I took a break and still like two hours later no succes. It still told me I had to check my router which I knew was a wrong message. So an error in an error message... well.
d) I kind of gave up and thought this was bad. And as I am stubborn I tried my phone. Same result. Hmm, tried a few times over and one of the times via my phone (still on the webinterface) it succeeded in finding the router, so I pressed save. By now it had been working for like 4 hours although it told me it did not and that I had to check my router.

f) So I didn't care much. And went to bed.

g) Next morning my phone finally made it all the way. At first a manual set up, but then a little later I could have the automatic setup that I am using now.

So now you know why "patience" are the missing keyword. The change of device may be another.

And the only thing I really would like to see was that it was a waterproof device (yes I do have outdoor electricity sockets).

Well, I did look at those, but two things made me not go that way: a) the need power over ethernet (as far as I can se) so I would have to cable outdoors (I already have the electricity there so I do not have to do anything if it was usual power supply) and b) they are never mentioned as extenders but only as routers. I have to use an extender as I get a internet from a radio/TV signal (450MHz) .

I know the issues around humidity, but setting a waterproof junction box up with the extender in is a very cheap way to go. By the way the extender already reaches pretty far from indoors behind a three layer window.

 

So I still follow this track. I have bought one extender more to daisy chain them (or maybe the 2nd one will end jumping between the router and the extender - I cannot tell until I get it to play with) so the 2nd one first of all cover my 2nd house indoors, but also that the two together make a even better coverage outdoors when the weather is like staying out. At that time I am certain that the waterproof junction box(es) also may be used.
