Things that may impact your internet speed:
Placement matters
Place your gateway or wireless router in a centralized spot in your home. Keep it out in the open. Avoid cabinets, closets, and places that may accidentally get covered up (by a pillow, backpack, jacket, etc.)
Consumer device capabilities
Some Internet Speeds are faster than many devices can handle. Check out this list of consumer devices and expected wireless speeds.
Stay current
Are your operating systems for your computer or laptop and Internet browsers up to date? To achieve the best results, make sure they are. Also make sure that you have an up to date modem and gateway.
Friendly reminder
Wireless speeds are typically slower than wired connections due to wireless hardware limitations, the distance a signal has to travel and potential slowdowns along the way, including walls, windows, large pieces of furniture, etc.
