I have been trying to trouble-shoot a specific issue on my own for the last couple of weeks. I have seemingly exhausted all options available to me.
I have a My Net N900 router with several devices attached, both wired and wireless (mostly wireless). I have a cable modem (Time Warner Cable - Ultimate: 50Mbps)
Everything on the network works great until I connect my work laptop to the network. Within minutes of connecting it, I lose wireless connectivity from all of my other devices, including the work laptop.
I am able to see my home network (and access the router admin) but I can’t access the internet.
- I can access the internet from all devices through WiFi when the work laptop is not connected wireless to the network.
- I can access the internet from my work laptop if I turn off WiFi and connect it via Ethernet cable.
- I can access the internet from my work laptop on other WiFi networks.
- I can access the internet from all devices through WiFi after I disconnect the work laptop (usually have to power reset the router to recover).
Trouble-shooting options I’ve tried…
- Rebooting the cable modem
- Rebooting the router
- Updating the firmware (current version is 1.07.16)
- Verifying signal is strong through the cable modem (Time Warner Cable)
- Disabling WPS within the router admin (Advanced Settings > Wireless > Wi-Fi Protected Setup)
- Disabling FasTrack Plus QoS within the router admin (Advanced Settings > Additional Features > FasTrack Plus QoS)
- Disabling Enhanced WMM within router admin (Advanced Settings > Additional Features > Enhanced WMM)
- Changing the ‘Channel’ for 2.4Ghz from Auto to Channel 1 within the router admin (Advanced Settings > Wireless > Wireless Setup)
- Cloning the ‘MAC Address’ by clicking on the “Clone Your Computer’s MAC Address” button within the router admin (Advanced Settings > WAN > Internet Setup)
NOTE: I feel like this issue may have cropped up after I updated the firmware (as there was a point in time when I didn’t have this issue), but I can’t be sure.
