Back in March our wireless speeds slowed to a crawl (0.58 down/1.99 up). Verizon wouldn't help me bcs the wired desktop speeds were fine. So I was looking at my router settings and realized I never upgraded our security from WEP to WPA. I did that and our wireless speeds went back to more normal levels. But now several devices lose their wireless signals within 24 hours- specifically a printer and a tivo network adapter. If I change the channel on my router they all reconnect. Our laptops seem to be fine so it's not every device. Does anyone have any thoughts? We have the actiontec MI424-WR.
