I have a Netgear Nighthawk AC1900 DST router that I bought about 4 years ago from Best Buy. It came with a DST adapter so I can have enough range to reach my office computer in my basement. A few months ago, my DST adapter stopped working but my router can still barely reach my office. Now that I am working from home, I was hoping to get my wifi in my basement office to a stronger signal. the questions I had were: Is my Nighthawk AC1900 router still adequate? If not, any recommendations? (need to consider a budget as my wife's hours have been reduced) Can I get some sort of help/tech support on my DST adapter even though the geek squad support ended a couple years ago? If I can't fix my DST adapter, what would be a good extender without breaking the bank.
