EA3500 Bad Gateway - Another flavor

Hi Folks.

 

Having my own set of Bad Gateway issues with my EA3500.  I've read the other posts here, but need to give my flavor. Since I cannot access the admin page, I cannot tell you what firmware version I have.

 

From multiple devices, both wired and wirelessly connected to the router, I cannot access the admin page (192.168.1.1) - "502 Bad Gateway".  I disconnected from the WLAN so the router is an island, and went through the reset procedures.  From there, I was able to access the admin console, and re-establish all my settings, including the 8 devices we have in the house and parental controls (my primary purpose).

 

Not that I've logged out and it's been 10 minutes, and I'm back to the Bad Gateway error on the same machine I used hardwired to the router to set it up, both hardwired and wireless. 

 

I cannot got through this process every time I need to tweak a setting.  I doubt its the windows firewall, because I was just connected to the router with the same settings.

 

Any other ideas?

 

Thanks (and happy new year!)

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
What ISP Modem service link speeds UP and Down do you have?
By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
Check cable between Modem and Router, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

Is ISP Modem/Service using Dynamic or Static WAN IP addressing?

For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

If the ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>http://www.practicallynetworked.com/networking/fixing_double_nat.htm and http://computer.howstuffworks.com/nat.htm If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ. Disable any ISP modem WiFi and filters like firewalls and such. Also check the routers DHCP IP address maybe conflicting with the ISP modems IP address of 192.168.1.1. Check to see if this is the same on the ISP modem, and if modem can't be bridged, change the Linksys router to 192.168.0.1 or .0.254.
