What does this mean? Is it a problem

Arronleeds — Thu, 11 Sep 2014 23:11:03 GMT

In the router log there are lines that say, blocked one more packet (because of packet invalid in connection)
There are also lines that say they have blocked 9 packets. I have some knowledge on Vdsl but I don't have any idea why packets are been blocked.

Hi Aaronleeds,

The blocked packets, will be the router blocking packets of incoming traffic not your outgoing traffic.

I hope this helps

Mark.

Thanks for the info, is there anyway to stop it from blocking packets? Or is this normal. I checked the ip it's blocking packets from and it's my iPhone. Thanks

The firewall part of your router will block and silently drop malformed or incomplete packets received over a wi-fi connection - this is absolutely normal as you don't want corrupted packets (and hence data) in your connection. Because of the nature of radio-based network connections, mangled packets are a normal part of a wi-fi connection and the systems is designed to ignore these and request re-transmission if required - the retransmit requests don't make it into the router logs, so you'll not be aware of them.
