Router ZyXEL HW -D1, Laptop win 7. After several days of good wireless connection PC losing connection. It discovers routers but unable to connect. Trying to restart router, to change security settings WPA, WPA2, WAP, no security at all but all in vain. Same time when there is connection, all above security setting work without problems. With ethernet cable there is no problem and Internet connection is always available. All 4 lights are always green at the router not showing any problem. Installed latest firmware for ZyXEL. No difference. Just after some time of normal operation wireless connection got lost. After another several days of various changes, tries connection coming back. Would you help me, please. Hardware? Router is abt 5 years old.

1. this issue may be due to the age of the router and also firmware updates need as it reads
2. check the manufacturers site for update instruction set
3.Here are some step to try to see if the router is indeed grandfathered:
1.Log into router. Using either 192.168.0.1 to 192.168.1.1 in a browser window that is ( internet Explorer or Firefox)
2. Verify wireless router name( on the computer) >>> ( on/off) ( router status window)
3.Note router name you are connecting to.
4.. Check the laptop/desktop do ipconfig /all to see current IP addresses.
5. Set the laptop up in the router by WEP KEY or MAC address. This set up in the "security tab" in the router. using 192.168.0.1 or 192.168.1.1 to access through a browser.
6.Note router name you are connecting to.
7. Move the laptop about 20ft away and try to log on to the internet.
This is for all routers to set up wirelessly.
8. check for firmware update at the manufacturers site for your model router
9. cell phones, cordless phones, digital TV's, can affect the data signal from a router. Also distance from the router can be a factor. If your router is in a basement place the router to a upper floor and center it in the room.
