Windows 7 Wireless only connection on a wired PC with no adapter

[Chowda]

Hi guys, really need your help.

Win7 64-bit

So a week ago I needed to have access to a printer/scanner (Brother) in my home. I installed the software/drivers and unplugged the ethernet cable from one of the modem ports into a Linksys router. Everything was just fine except anything over the internet became slow. I plugged the cable back in to the modem, no change.

I've speed tested the connection on my PC its 3-5mbps. On the other computer its 25-35mbps, the normal speed.
What is most interesting is that my PC no longer lists itself as the connection as Wired, its always Wireless with the network name. My PC is an Asus CM6870 and I have no wireless adapter.
I have uninstalled the Brother software and unpowered the router, no change.
I have gone to Network and Internet and tried creating a new connection, it says the modem or other device error.
I have been searching online and one tip was to go to Device Manager and uninstall the modem driver. I did that and it can't detect anything to reinstall a driver (it was just Standard Modem)

I can only believe that this problem occurred from the printer software. I've called my ISP and they believe its the modem and want me to send it in.

25mbps+ now I'm lucky to get 5mbps. Wireless on a PC with no wireless adapter and to the router its not connected to. Any help is greatly appreciated.

It sounds like you're experiencing network issues on your Windows 7 PC after installing Brother printer software. The sudden slowdown in internet speed and the incorrect network connection type are indicative of a potential software or driver conflict. Here are some steps you can take to troubleshoot and resolve this issue:

Troubleshooting Steps:​

1. Reset Network Settings:
   • Go to "Control Panel" -> "Network and Sharing Center" -> "Change Adapter Settings."
   • Right-click on your Ethernet connection and choose "Disable." Then re-enable it.
   • Check if your PC now recognizes the connection as wired.
   []Check Network Adapter Settings:
   • Ensure that your Ethernet adapter is set as the primary network connection.
   • Go to "Control Panel" -> "Network and Sharing Center" -> "Change Adapter Settings."
   • Right-click on your Ethernet adapter and set it as the default connection if it's not already.
   []Check TCP/IP Settings:
   • Open "Command Prompt" as an administrator.
   • Type ipconfig /flushdns to clear the DNS resolver cache.
   • Type netsh int ip reset to reset TCP/IP settings.
   []Update Network Adapter Driver:
   • Go to Device Manager -> Network adapters.
   • Right-click on your Ethernet adapter and select "Update Driver Software."
   []Check for Malware:
   • Run a full system scan using your antivirus software to rule out any malware affecting your network.
   []System Restore:
   • Consider performing a system restore to a point before you installed the Brother printer software.
   []Check Network Configuration:
   • Make sure the network settings on your PC match those of the working computer (e.g., IP address, subnet mask, gateway).
   []Temporary Testing:
   • Try connecting your PC directly to the modem to see if the issue persists without the router in the setup.
   []Check Router Configuration:
   • Verify if any settings on the Linksys router could be causing the issue.
2. Contact Brother Support:
   • Reach out to Brother support for assistance with their software potentially causing network conflicts.

     Additional Considerations:​

     • If your ISP insists on sending in the modem, you might have to go through their troubleshooting process.
     • Double-check any recent changes in software or hardware configurations that coincide with the network issue.
     By following these steps, you can isolate and resolve the network issue on your Windows 7 PC. If the problem persists, it might be beneficial to seek further assistance from technical support or a professional to diagnose the specific cause of the slowdown.
