Re: please help am i being Dossed muliple router disconnects

Hi @chris300,

 

I'm sorry that you're experiencing drops in connection and for any inconvenience that this is causing you. The logs above don't necessarily indicate that you're experiencing a DOS attack as it could be the router creating a false positive when the connection drops, but I'd recommend changing your router's password if you have any concerns.

 

Having tested your line today it appears the dropping connection issue may be due to a setting being incorrect.

The signal to noise ratio (SNR) is too low for the length of your line. The SNR helps the line to remain stable and unaffected by noise or interference on the line. The higher the setting for SNR, the higher the level of noise can be tolerated.

The SNR for your line was set too low for the amount of interference we'd expect to see, so by increasing this we expect the connection to now stabilise and for the information to be received without interference.

 

Please keep an eye on your connection over the next few days. If the connection issue persists, please run through our troubleshooting guides here and let us know how you get on.

Re: please help am i being Dossed muliple router disconnects

Hello @chris300,

 

Thanks for getting in touch and we are sorry to see that you are experiencing issues with your connection. It certainly is dropping more than we would like, however our tests are not picking up anything external causing the issue.

 

Please can you plug in your equipment into the test socket by following the guide here. Once in test socket please monitor over 24 hours and if the drops continue, please raise a fault here.
