Wifi signal light blinks and won't connect to device

re notify service / seller new doesnt mean free from defect

Restart your device.

If it is your WiFi, unplug everything involved with it for 30 seconds and then plug it all back in.

Make sure wifi is turned on.

Make sure that you are trying to connect to a WiFi signal that you know you can connect to. Not all WiFi signals are ones we can connect to with our tablets, phones, and computers. Try connecting to another signal, or try having another device connect to the one you can't connect to to see if it is a device trouble, or an individual WiFi signal issue.

Things That Affect Wireless Router Signals

1. Many wireless routers are using the same wireless channel. Many manufacturers choose channel 6 as the default. Change to another channel.
2. Analogue video senders used to send audio and video to other TVs in the home.
3. Microwave ovens emit interference in the 2.4GHz band.
4. Wireless speakers and console controllers can cause interference with the wireless router.
5. Bluetooth devices, newer Bluetooth devices can jump to different frequencies if there is a connection problem.
6. Power cables located near the wireless router can cause dropouts and speed reduction.
7. Fish tanks and mirrors will cause massive Wi-Fi shadow on the other side of the tank from the wireless router.
8. Depending upon the location of large mirrors will reflect wireless signal away your computer.
9. Building materials will block wireless signals such as plasterboards with metal foil, reinforced concrete walls and floors. Also objects near the wireless router such as metal filing cabinets and other electrical appliances.
10. Blinking Christmas lights can reduce Wi-Fi performance by 25% when it is close to the wireless router.

Unplug the ISP modem and the 2wire, Check ALL cables and reseat connections, plug in the ISP modem, wait for selftest, plug in wireless, wait for selftest, does your wireless SSID show in Available Wireless Networks on the Laptop? Can you connect using a Ethernet cable to verify it's getting a signal? Contact your ISP and have them verify the signal, have a ISP tech come out to analize the signal, it may be outside?

Sounds like a bad ground to me, although i am no expert.
i would be checkinh all connections and take it from there, a little wd40 might just solve it short term.

The orange WiFi light on the printer indicates that the printer is not connected to any network or trying to get connected to a wireless network when it's blinking.
Execute the Lexmark Wireless Setup Utility and make sure to enter the correct encryption keys if your wireless network is secured.
Make sure to allow full access to all Lexmark software and printer communication processes in the program rules/permissions for your firewall.
Place your printer where it receives excellent wireless signal quality and away from other electronic devices which can cause wireless interferences (e.g. cordless phones, microwave ovens, baby monitors, garage door openers, and other wireless electronics).

Check for the settings of your wireless theres a setting there that automatically search wifi networks by if incase cannot connect it will disable it self.. Also make sure that the wifi that you are trying to connect has a very good signal..

NEED TO GO IN CONTROL PANAL LOOK IN NETWORKING AND SHARING, DEVICE MANAGER, CHECK ON SERUITYS AND FIREWALLAND IF YOU ARE ON A LABTOP IS TO CHECK THE SWITCH TO MAKE SURE THE WIFI IS WITCHED ON.

If you want to use wifi only when your at home you can go in and manually disable the cellular data so the internet will only be wifi based. Probably saving you MB's and data cost.

Go to Settings, General, Network, then simply turn off the Cellular Data. Then it won't connect anymore to the cell data and rely only on wifi when your connected to it.

And simple follow the same steps and revers the process when your out on the go.

Thanks
