Common Issues related to AT&T Internet
Check wired connections and filters
You should always check wired Internet connections prior to troubleshooting Wi-Fi issues. Give us call for any ATT Internet Support. The support provides various help regarding any kind of internet issue.
Check your connections
Wired connections may vary based on your equipment.
- Check the Wi-Fi gateway electrical connection (not a surge protector).
- Make sure the power is On.
- Secure all wired connections between the gateway and your PC. '
If you have traditional phone service or telephone equipment plugged into your telephone jack, you need a filter to receive the AT&T broadband signal. Depending on how many devices you have, you may need additional filters.
- Make sure all jacks with phone devices have a single-port filter installed. To be sure the filter works, plug in your phone and listen for a dial tone.
- Make sure the jack where the modem or gateway is installed has a dual-port filter and the modem or gateway is plugged into the DSL/HPNA side of the filter.
To avoid a weak Wi-Fi signal:
- Place your gateway in a central location in your home.
- Set up your gateway at least three feet from other appliances that send wireless signals such as microwaves, cordless phones, and baby monitors.
- Keep the gateway from being directly against a wall or in a cabinet.
If you still have signal issues, there could be a problem with your computer or device’s wireless adapter.
Confirm the Power, Broadband, and Service lights on your gateway are green. If your lights aren’t green, you may have a problem getting a signal or your gateway may be having a problem.
Power cycle your modem or gateway by unplugging the power cord on the unit from the wall outlet, and then wait two minutes before plugging it back in.
Equipment, browsers, and additional help
If your gateway and connections are all good, check your computer or device.
- Reboot your computer or device.
- Make sure your Wi-Fi settings are correct and the wireless adapter on your device is turned On. Refer to your manufacturer’s documentation for device-specific instructions.
- Reduce the number of active devices connected to your home network.
- Close any unused apps, programs, or browser windows.
- Clear your Internet browser cookies and cache to free up temporary storage of Web content.
- Check your browser's connection settings to make sure there are no proxies or filters in place that interfere with your ability to browse the Web or check email. Your browser's support site can instruct you on how to do this.
- Temporarily disable your firewall to determine if it interferes with your Internet connection. Don’t forget to enable when you’re done testing. Only run one firewall at a time.
- Run anti-virus and anti-spyware software. Malicious software can deplete your computer's system resources. If you don’t have anti-virus or anti-spyware.
