[SOLVED] Can't access default gateway or see wireless devices from wired computer

Hi all,

I regularly stream content from my desktop PC to my various wireless devices (Chromecast for video, Shield tablet for games, etc.). However, recently I haven't been able to see those devices from my desktop computer or vice versa. Digging into it, I've found that I am not able to access my default gateway to access my router config settings either. I'm assuming the two are related.

Current setup:
Modem connected to WAN port on router (Linksys E2500). Desktop computer is wired into LAN port (I've tried all 4 ports). Various other devices (tablet, phone, chromecast, etc.) connected successfully wirelessly. All of my devices, including my wired desktop, can access the internet fine.

What I've found so far:
-Accessing default gateway (192.168.1.1) on my wired desktop from any browser gives "This webpage is not available". I've tried http, https, specifying port, etc with no luck.

-Pinging '192.168.1.1' from the command line does connect and get a response. Also, I looked up the local IP addresses for my chromecast, tablet, and phone, and am able to ping all of those addresses successfully as well.

-I *can* access my router's config settings on my wired desktop by accessing my public IP address (googling what's my ip?) in browser.

-All my wireless devices are able to access router config directly through the default gateway, as well as communicate with each other (ex. tablet recognizes chromecast).

-I hooked my work laptop up wired to the router, and it was able to access the router through the default gateway in browser, aswell as see devices such as chromecast. This makes me believe it's an issue isolated to my desktop, and not the ports on the router.

Relevant Information from ipconfig on desktop:
IPv4 Address: 192.168.1.149 (this is within range of the DHCP ip range settings on the router)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DHCP Server: 192.168.1.1

Network Adapter Settings:
Both IPv4 and IPv6 are set to automatically get IP address and DNS address settings.

I've reset my router to factory settings multiple times, purged and re-installed my network drivers, power cycled entire system, updated router firmware, etc. I'm lost at this point.

Thanks for reading this far, any and all help is appreciated.

Found the issue, posting here in case anyone else happens to run across this with a similar setup. Seems getting some sleep and approaching with a fresh mind helped.

I was able to dig up an ancient wireless usb adapter and tried that on my desktop. Connected fine to everything, allowed my desktop to see other devices, etc. This pretty much confirmed it was my desktops LAN port/drivers.

I use a Killer e2200 ethernet card, and it comes with some bandwidth/network controlling software. Digging around, it seems that software is known to cause a wide assortment of issues. I uninstalled my network drivers again, but this time made sure to also uninstall the killer network software suite. After uninstalling I used CC Cleaner to clear out any traces of it in the registry files and restarted.

Per the thread here (https://forum-en.msi.com/index.php?topic=178064.0) I was able to find that my motherboard manufacturer also offered standalone drivers *without* the software suite. I downloaded those from my specific motherboard support page and installed them "manually" through the device manager without the software bloat. Since then, everything appears to be resolved.

Unfortunately that doesn't allow me to still use the software for the card, which admittedly was pretty nice since you could bandwidth control specific apps, but since I don't use it often (and I'm sure there are alternative apps somewhere) I'm going to take my working network and leave it at that. I suppose someone could try reinstalling the software suite after purging it, perhaps it was just corrupted and needed a new install.

This statement seems troubling to me. Does the desktop connect via VPN? Have you checked to see there is a proxy server configured in the browser? Have you tried a different browser?

If you can access the router settings via your public IP address, that could indicate your router (and therefor your network) may be exposed to the Internet.

Edit: good to see that you found the problem.
