The mobile router function has long existed on all popular operating systems, so today's gatherings will be devoted to its use by ordinary users.
Now, when a smartphone can easily work for several hours in Wi-Fi router mode, separate gadgets for these purposes are becoming less and less popular. I myself occasionally use this functionality, but today it came in handy. An Uber driver drove up and complained about the poor performance of the mobile internet in the area, which prevented him from even starting the ride. I offered to distribute the Internet to him using my smartphone so that he could start the trip without any problems (you could, of course, resist and ask him to go without starting the trip, but I believe that the human attitude should be mutual, and if we want the taxi to be polite and responsive drivers, you should be the same passengers). I use a complex Wi-Fi password, but during the trip I quickly changed it to the standard combination '12345678' so that I could dictate it easily. On the way, it turned out that the driver just had an old SIM card, and his tablet supports LTE and he has the same operator as me. I recommended him to replace the SIM-card in the operator's salon, he thanked for the advice, drove me home, and then we parted.
And tonight I remembered that sometimes I use Wi-Fi from my mobile without a password at all (usually these are occasional situations when the Internet is needed literally for 10-15 minutes) and I was curious, and what password do you usually set, dear readers? And how often do you use the mobile router option itself? Please share your experience in the comments.
