Hey guys,

I'm having a bit of trouble. My girlfriend's netbook, an Acer Aspire One D257 running Windows 7 32-bit, has randomly stopped connecting to the Internet. I am able to connect fine from my laptop though.

All the latest wireless drivers are installed, and I've tried removing the connection then restoring it, but it just connects with no internet access for a few seconds then disconnects again.

Any help is much appreciated. Thanks in advance :)

A short, practical summary and follow‑ups based on the thread: reported the netbook started working after a DNS flush and several router restarts, which strongly suggests the fault was on the router side (DHCP/firmware or a transient router crash) rather than the netbook hardware. and were on the right track — flushing DNS and checking IP configuration are useful diagnostics — but when a restart fixes it permanently, focus first on the router. (cisco.com)

Things to do on the router now (to avoid recurrence): update the router firmware, check for scheduled reboots or automatic firmware-update settings, review the router’s system log for crashes or DHCP errors, and try a different power outlet or power adapter if the router reboots unexpectedly. Back up the router configuration before making big changes. Vendor support pages explain these steps and common causes for routers that restart or drop clients. (asus.com)

PC-side checks that complement what was already tried: disable the adapter’s power‑saving option in Device Manager (so Windows won’t turn the radio off), and if problems continue reset the Windows networking stack from an elevated prompt and then reboot. Example commands (run as Administrator): 

netsh winsock reset
netsh int ip reset

Microsoft documents these as standard troubleshooting steps for persistent connectivity faults. (support.microsoft.com)

If the issue looks wireless-specific, scan for channel congestion and move the AP to a clearer channel (or use 5 GHz when possible). A simple Wi‑Fi analyzer or apps like NetSpot will show crowded channels and recommended choices; switching channels often stabilizes intermittent disconnects in dense environments. (netspotapp.com)

If the problem returns, test with an Ethernet cable to isolate router/ISP vs Wi‑Fi/client, and only then consider factory‑resetting the router (after saving its settings) or contacting the ISP/vendor for firmware/hardware replacement.

Try opening the run command pressing (windows key+R on keyboard) then type cmd, hit enter. Once in command prompt type "ipconfig" /flushdns" to clear name resolution to the Internet. May also try removing the SSID and re-adding to her computer.

Also, type IPCONFIG /all on both computers, compare the IP settings. They should be the same except for the IP address. The subnet mask, gateway, Dns settings need to be the same. If they are not, someone may have configured static information on the computer that is not working.

Also, check the malware program on the computer. Is it up to date, any settings that may be blocking access to the internet?

Hey guys, thanks for your replies, managed to get it working a few days ago, tried RTFMID10T's suggestion, and after restarting the router a few times it started working again :)
