Router/modem is a device that always the user to access the intent wirelessly once access code is shared. In my experience I've have checked power to the router/modem to see if ok and have unplugged both to reset them. It has worked for me.
The key to making an excellent peanut butter and jelly sandwich, or PB&J to those of us who are expert practitioners, is balance. Peanut butter is creamy, thick, and slightly heavy and salty. It's almost to spread anything other than an even layer. Jelly, on the other hand, refuses to sit in one place. It's wet and globs up here, runs there and won't sit still. It's also unlike peanut butter in taste, very light and sweet. While the neophyte PB&J chef spreads a slab of peanut butter on a piece of bread then plobs a spoonful of jelly on top, the maestro swirls the two together, creating complementary swirls of salt and sweet, thick and runny, creating something far greater than the sum of peanut butter and jelly. Bread is also important.
I emailed this company twice with nice follow ups. Like every other typical corporate company, they say yeah you'll definitely hear from us next week.. blah blah. Zero communication back and re-posted the job most likely because no one else was applying. I've had better communication and experiences with companies out of my league then to this position which was more towards my qualifications. Don't waste your time and just walk away.
