Tons of error messages in event log and connection drops

[GrantyM8]

As the title says, I have been getting loads of errors in my router event log. I know that there are usually some to block common spam attacks and what not but there are some which say some very odd things and I need somebody to help me understand what's happening. Along with the errors come frequent connection drops and temporary stalls. I would attatch the log to this post but I don't see an option to do so. Any help would be greatly appreciated thanks!

If you're service is also dropping @GrantyM8, we may need access to your account to make sure everything is set up correctly at our end. As we're unable to complete security with you via a public forum such as our Community, please pop us a private message through one of our social channels and we'll take a look into both the messages in your events log and the reason for the drops in connection.

I wouldn't worry too much about the error log, that is always full of worrying messages, unless you fully understand them.

 If you have tried with the router in the test socket, and still get the drops, then call Vodafone on 08080 034 515 or use live chat https://www.vodafone.co.uk/bbservcd/
