I am trying to solve this problem for a while but still can not solve. So I moved to US from South Korea with a router from LG (yes old, Korean one). It was fine for years, and about like an 8 months ago, I moved to a new house. I had Time Warner Cable since the beginning and first about 5 months or so were fine. but all the sudden, my wifi is getting disconnected like every 20 minutes or so. I asked Time Warner for some help and they told me to type some of the command prompt (assuming something was wrong here) and when they came to my house, they did not have any particular solution but router (which I highly doubt). How can I check the problem and how can I solve the problem?
