WNDR4000 - Blocking Admin Access After Latest Security Update
I updated the firmware in response to a notice I received from Netgear about a security fix. Now, every time I adjust the various settings and the router reboots it blocks my access to the admin pag...
I just applied the latest Firmware (1.0.2.6) update as well, I don't recall the previous version, but it was a much earlier version 1.0.0 (not sure of the last digits). After the update and installation completed (which was applied by direct ethernet connection, i.e. not WIFI), I can no longer connect to the web Administration Page via the default gateway IP address. What's odd is all my setups remained in tact after the Firmware update was applied, including the authentication credentials. If I run an IPCONFIG, the settings for DHCP, Gateway, etc are all as was on my directly connected laptop. But, when I first re-open the admin page using the default gateway IP address and authenticating I receive the message "You are currently logged in from another device. There can be only one device logged in at a time. If you log in from this device, the other device will be logged out. Do you want to proceed?", as I was in the same, or original browser session when the firmware update was applied I clicked "yes" to proceed, after which the connection fails to open the adminstration page. I tried different browsers (Chrome, IE), still no access.
I powered down the router, restarted, entered gateway IP address to connect to admin page, authenticated as requested and the same warning message appears ... "You are currently logged in from another device. There can be only one device logged in at a time. If you log in from this device, the other device will be logged out. Do you want to proceed?" But, this time, choose "No" and the response page displayed a conflicting dynamic IP address, which is different from the dynmamic IP address assigned to the laptop. which I applied the firmware upgrade from. On a whim, I turned off my WIFI connection on my cell phone. I tried to ping the new, conflicting IP address assigned and the request timed out. I then tried to connect to the administration page using the default gateway IP address, SUCCESS.
Bottom line, check what other device may be connected, which I was able to determine by choosing "No" to the Do you want to proceed?

Which "the various settings" are you adjusting (to what)?

Which "a static IP address"?

That would certainly be an interesting experiment to run.
I updated the firmware to the latest version WNDR4000-V1.0.2.6_9.1.87.chk
I don't recall the previous version, but it was the most recent prior to this security update (I imagine that this model woud not normally have any additional updates due to its age).
The various settings would be SSID and wireless password. I normally limit the DHCP scope as well, but I can't get that far with the configuration as the router resets itself after setting up the security. Once the router resets, I cannot access the admin web page nor connect via Genie.
I set a static IP address on my PC (e.g. 192.168.1.10) so that <hopefully> the router would not think that a different device is trying to log in.
Again, the router is functional but I cannot administer it after the first reset.
This is clearly some kind of glitch with the latest firmware (I might give dd-wrt a shot before throwing this one away).
