Ive always found D-link gear to be flakey and I worked for a ISP provider and we used to give those out free but a lot came back. Id never buy one again. Netgear is pretty solid. Agree with taking back. If I buy something that turns out to be utter rubbish no way I want the same again. Nothing eases my irritation like a complete brand swap.
. Sometimes brands go into a cost reduction death spiral cheaper and cheaper components leading to lower market share so they cost reduce more and make it even more crappy then they give up and leave the market. Partly consumers take part of the blame by being intensly focused on price. Me I would rather have a older device that is a brand I trust rather than a newer cheaper brand in the cost down spiral. Points to Toshiba laptops though the plastic got thinner and nicities like a CMOS battery deleted off the motherboard (LOL) they were still reliable. Unfortunately they have given up on the spiral of doom and are sticking to business computers for now. Everyone buys a el cheapo HP notebook. I worked for a computer reseller. My daily tasks involved a endless stream of faulty HP products (laptops, desktops, tablets). Theres a reason they are cheap. Not saying Toshiba was perfect but you had a much lower chance of a bad experience with them.
