G'day all.
Does anyone know of a wi fi router which can be purchased, received, unpacked, plugged-in, powered up and will provide constant connection on standard adaptors WITHOUT having to undertake a language course of 'Geek-Speak gobbledy gook'?
I am AGAIN attempting to get internet connection via wifi link to a router (which connects perfectly on ethernet cable) but which refuses to make a wireless connection, citing 'authentication problem'.Over the past 10 years, or so, I have attempted this feat with a number of different routers with a (non-repeatable) success rate of approximately 5%!

The routers - BT, Orange, Thomson, D-Link et al have all worked when cable connected and ALL either failed or were totally unreliable for wireless communication. Querying the symptoms on-line, produces a totally unhelpful collection of aforementioned Geek-Speak, acronyms and associated 'unwisdom'. Allowing my ISP to remotely attempt a fix was similarly unsuccessful. Particularly galling is that the devices can 'see' and connect to other local 'hot-spots' but the signal strength is unusable.
Is it REALLY not possible to purchase a SIMPLE device to accomplish this?
