I have recently bought the new kindle fire hd and authenticated it to my home wireless, okay that worked after I turn off both the kindle and wireless modem and turned them both on at the same time. The problem is now that everytime I do this and my son uses the kindle my laptop wireless automatically shuts off and gives me a messae telling me that I have somehow cancelled my wireless connection. The only way for me to re-establish laptop wireless connection is to turn off the kindle, plug in my ethernet cable into the modem and restart the modem and computer at the same time and reconfig the wireless. Can someone please tell me how to fix this so that I can use my wireless for both the kindle and laptop without having to reset the modem each time. Oh, and before anyone asks I have set my sons DSI to my wireless before and run them both at the same time without a problem, so more than one device can run on the wireless.

reported that the Kindle joins the home Wi‑Fi but powering it on later causes the laptop’s wireless to drop, and correctly asked whether IP assignment was involved. This symptom most often points to one of three root causes: a DHCP/address conflict (two devices ending up with the same IP), the router’s DHCP service or client table failing when the tablet joins, or a firmware/compatibility bug in the router. The goal of the steps below is to reproduce the failure, confirm which of those is happening, and work around or fix it without rebooting the whole gateway each time.

Try these steps in order:

  • Log into the router admin page and watch the DHCP client list while you turn the Kindle on. Note MAC addresses and IPs to see if an IP appears twice or if the DHCP list momentarily clears.

  • Instead of restarting the modem, try renewing the laptop’s lease. On Windows open an elevated Command Prompt and run:

    ipconfig /release
ipconfig /renew

    On macOS use System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease. If renewal restores connectivity, that strongly implicates DHCP handling rather than the laptop’s radio.

  • Reserve addresses (DHCP reservation) for both devices by binding each MAC to a fixed IP in the router. This prevents collisions without forcing static IPs on the client.

  • Update router firmware and the Kindle’s system software. If the router was provided by your ISP, check with them for known issues or a replacement gateway.

  • As tests, temporarily disable any client/guest isolation, try a different SSID/band, or reduce wireless mode (e.g., b/g/n mixed) to check for feature incompatibility.

If none of those steps resolves it, collect the router’s logs (or enable syslog) and contact the router vendor — some older or buggy gateways will need replacement. Back up router settings before any factory reset.

When you say you "Authenticated" it into your home network, what did this involve? (in general terms)

Have you assigned IP addresses to those devices in your Router? Can you, in general terms, tell us what you did, please?

My Wi fi is security enabled so I just added the security code and parameters (WPA-2 Personal and AES) in the connection settings.
