A powerline networking adapter transmits an Internet signal over your home’s electrical wiring, it’s a good way to get Internet access to a distant part of your house. If you only have about $50 or so to spend, our budget pick is on sale for a new low price of $44. The TP-Link TL-PA7010P doesn’t offer top speeds, but it gets the job done reliably and cheaply. It almost never sees discounts, so even though this isn't a significant price drop, it's the only one we've ever seen. We wouldn’t recommend it for streaming 4K video but it's more than fast enough for everyday Web browsing.
