Quick summary and practical options. You can turn the PC into the internet gateway (software hotspot / Internet Connection Sharing) and then attach a second device to the PC’s Ethernet, or you can make a second router/AP join the existing network in bridge/client/AP mode so it rebroadcasts Wi‑Fi on the wired side. and were on the right track — both software and router-as-AP approaches work, but the setup details matter.

If you want to use a spare router as an access point, follow this checklist:

  • Reset the spare router to defaults so no weird settings interfere.
  • Give it a fixed LAN address that won’t conflict with other devices (pick one outside whatever DHCP range your PC or primary router uses).
  • Disable the spare router’s DHCP server so it won’t hand out addresses.
  • Connect the PC’s Ethernet to a LAN (not the WAN) port on the spare router.
  • Configure the wireless SSID/security on the spare router and test with a phone or tablet.

If you prefer software sharing from the PC (the VirtualRouter approach mentioned earlier), try the OS’s built‑in hotspot/ICS first — it’s usually more stable than third‑party tools. If the sharing app crashes or the adapter overheats, update the wireless and Ethernet drivers, install current OS updates, and test with a different USB or PCI adapter if available. A hardware AP is the most robust long‑term fix if software sharing proves unstable.

Troubleshooting notes tied to the thread: if plugging the Ethernet into the PC causes it to power off, stop and test safely — try a different cable and a different router port, test the cable between two other devices, and check the PC’s NIC drivers and power settings before continuing. Also look in the spare router’s menus for modes named “Access Point,” “Bridge,” “Client,” or “Repeater” — using the correct mode avoids double‑NAT and DHCP conflicts.

Not really. WiFi is a radio link. You can connect your PC's ethernet port to a WiFi router, and that can then be accessed via wifi-enabled devices, but you still only have one WiFi access point. 2 points == 2 devices, etc.

Thank you rubberman for your answear i appreciate it.

This looks like a job for (fanfare music) VirtualRouter. Since hijacking occurs here's the link.

Since you want to share your WiFi connection, this alone may do fine without adding more gear.

thank's rproffit,
i can actually share my internet using my wifi adapter, it's builded with the adapter software(edup ep).
but it start lacking sometimes, also the adapter get's hot !

Member Avatar for rproffitt

mouaadable, that app can share it to Ethernet which can use a WAP on. Remember that almost all routers can be turned into a WAP. Google "How to use a router as a WAP."

As to the hot WiFi, at the office with some 100 laptops, none seem to have that trouble. Strange issue?

oups, i didn't know that!
but anyway it gives me"virtual router manager has stopped working" every time i try to start it !

i tried to change my router settings manually:

router im trying to use as a WAP :
ip : 192.168.1.130
subnet : 255.255.255.0
gateway:192.168.1.100

dns : 192.168.1.1

wifi adapter :
ip : 192.168.1.120
subnet : 255.255.255.0
gateway : 192.168.1.1

dns : 192.168.1.1

tablet :
ip : 192.168.1.135
gateway : 192.168.1.100

dns : 192.168.1.1

but no interent conx on the tablet, it only lead to the router gateway(192.168.1.100) when i use 192.168.1.100 as dns and no internet when i use 192.168.1.1 as dns.
i'm really confused i will get rid of everything and forget the idea of doing this

thank's alot guys

mouaadable, since I don't know your IP plan I can't see what's up. But the DNS is not one I'd use.

Besides the IP plan, the most common gaffe with using a router as a WAP is folk plug into the router's WAN port, the next is they didn't turn off the router DHCP.

THANK YOU ALOT rproffitt
i appreciate your help, i got new 3com router that i think it will work, but it come another problem, when i plug the ethernet cable to my pc the pc turn off...i will solve that problem and get back here with further detail and if it worked or not ...
