wifi range extender causes internet dropout when connected

Hi all,

 

I recently got the NBN connected ... and now I want to extend the range of my wi-fi to the back bedroom.

I connected my existing TP-Link extender and re-configured for the new network.  Worked for 5 minutes ... but then the internet dropped out.  All lights were still on ... on the Sagecom modem.  Connects to wifi ... but no internet.

Disconnected the range extender and had to hard reset the modem before I could access the internet again.

Tried a different wi-fi extender with the same result.

 

Any reason why the internet keeps dropping when a range extender is connected.

Really frustrating as it worked fine when I had a cable connection in my previous house.

 

Thx,

Gary

Re: wifi range extender causes internet dropout when connected

If you have moved the Range Extenders closer to the Modem and still have issues, and you haven't done the following to date, this may assist.

 

The culprit could be a new feature, not in previous older cable modems, called Beamforming which may be Enabled as Default in the Sagemcom - System Admin/Wireless/Advanced Features/Wl0=5Ghz page, go to bottom of the very long page and Disable the two Beamforming tick boxes , then Save. If your TP-Link Range Extender only supports, 2.4Ghz (n) set it to connect to the Sagemcom's 2.4Ghz SSID (slower but stronger signal)  - the one on the router label on the bottom. If the Range Extender does both the 2.4 Ghz and 5 Ghz (ac) and your TP-Link Configuration software supports connection to both bands, enter the 5Ghz details as well (will be the same as the 2.4 Ghz but will show a -5Ghz suffix). There are some good YouTube clips that show various installtion procedures for TP-Link models - A change of name for the SSIDs may depend on your TP-Link model or personal preference.

Re: wifi range extender causes internet dropout when connected

i don't use extender any more as it caused alot of problems for me in the past, from memory, having the same SSID can cause the issue. My suggestion is to do a factory reset on the range extender and using its factory setting including SSID, but change the passphase and see if you can get a stable connection.

Re: wifi range extender causes internet dropout when connected

I have a Sagecomm FAST5366TN-A modem. Where do I find this setting on the user interface?

I have been through all number of troubleshooting options, even with the range extender manufacturer TP-link and have massive issues with continuous drop outs between the extender and modem.

Re: wifi range extender causes internet dropout when connected

Hi - what is the model number of your TP-Link Extender please - is it set up with an Ethernet cable connected to the Optus modem or is it via Wi-Fi. Are devices dropping out when connected to the Extender or is the Extender losing connectivity to the modem - LED colour on the Extender may indicate this. If devices are dropping out, are they predominantly 2.4Ghz or 5 Ghz devices.

Re: wifi range extender causes internet dropout when connected

The TP-link is an RE650.  It is set up with wifi connection to the modem, because it needs to be halfway down the house. We can not have cables running down the stairs and across the house.

The lights are always on when I check the extender.  The devices usually say connected but no internet.  Some devices are 2.4ghz others 5ghz (phones, fetchbox, pcs, laptops).  Have tried using one band at a time and it doesn't help.  Have tried checking a wifi analyzer and setting channel, doesn't help. 

Some devices now not even connecting, such as the tv - I do a connection test. 

it checks access point connection- ok

Checks acquired IP address - ok

checks for devices using same IP address - ok

Checks gateway connection - ok

Check server connection - not ok

Hey @SarRic, although we are unable to advise on third party devices. I would recommend having a chat to our Tech teams attached above, whom would be more than happy to walk you through connectivity issues. 


If you were not aware as well, Ethernet cables can be purchased at different sizes should that be of interest
