Wireless connection speed decreases strangely

My wireless connection decreases from 56mbps to 1.0mbps for no reason after
half-hour. I'm using linksys router and tried power cycling the router but to
no avail. The only way I can do is to repair the connection and it returns to
maximum speed.

 

Have you tried testing actual throughput periodically, as in when you first
start out (max connection speed), then again when you are at min connection
speed. If you have noise (analog interference) or neighbours (digital
interference), you'll not be getting max throughput, regardless of connection
speed.

Some WiFi drivers may start your connection out at maximum expected speed, and
gradually decrease, looking for a stable connection. Depending upon the
interference that you may be getting, this could give you a steadily decreasing
connection rate. Do a WiFi environment analysis, and watch your metrics and
your neighbours.

Paranoia is not a problem, when it's a normal response from experience.

However, my other laptop using the same wireless router is running at full
speed. So there isn't any interference. Both laptops are using the same
settings.

 

what operating system? what NIC and what driver?
which Linksys router model number and hardware rev and what firmware
version?

Models of wireless adapters on both machines.
Band and channel set on the router.
