A solid mesh Wi-Fi system eliminates dead zones and handles dozens of devices without dropping calls. Plan on keeping it for four to five years, so buy enough coverage the first time instead of adding weak extenders later. New models drop every fall, which means last year's Wi-Fi 6 or 6E systems usually hit deep discounts while offering more speed than most home internet plans even deliver.
If your connection lags every time someone streams in the back room, a $300 budget gets you a top-tier setup. You don't need to drop all three hundred bucks at once if you use the right financing window.
Keep in mind that an intro window is a strict deadline, not free money. If you still carry a balance after those 18 months end, the regular APR kicks in on whatever is left, so set up automatic payments for $16.67 right away.
