Do I have a faulty hub 4?

Hi,

 

I've previously post about some problems with my HH4a - frequent restarts, frequent wifi disconnection, lots and lots of blocked entries in the event log never previously seen.

 

I've just experienced another issue and I'm now wondering whether a faulty HH might be responsible?

 

I have a PC connected via a cable to port 1.  The event log showed lots of lease requests and then 'host unknown (mac address removed) IP 169.254.xxx,xxx detected on interface eth0, port0'.   The devices showed on the network diagram as unknown but never appeared on the DHCP table despite refreshing.   

 

Previous the PC had shown as a named device with the normal 192.168.xx.xx range IP address and appeared on the DHCP table.

 

Could all this and the other issues I have experienced be related to a fault hub?  Is it rare for one to develop a fault?

 

Any thoughts appreciated as i've had nothing but issues since receiving the hub a few months back.

Home Hubs are cheap mass-produced things.  It's not unknown for them to develop faults.

 

A factory reset might help (or it might not).

I've tried a couple of factory resets previously but still having problems.

 

Do you know how I might go about reporting a faulty hub and obtaining a replacement?

 

Thanks,

Re: Do I have a faulty hub 4?

Thanks.  I'll give it a go.

 

One final thought before I do.   Whilst it's difficult to pin point, some of the problems (the frequent disconnects and invalid packets) seemed to have started when I was switched from interleaved to fast.   Is there an benefit in getting reset to interleaved first to see if this makes a difference?  If so, can I do this myself?

 

I'm still seeing lots of out block invalid packets in connection messages - including for odd websites I don't recognise.

Re: Do I have a faulty hub 4?

the blocking will be hub firewall doing its job not a problem

 

latency is automatic and fast is preferred for most people unless there are line problem but DLM would automatically change to interleaved

As per my reply to your previous post on the firewall blocking.

 

To give an indication of what I was talking about, here's the list of servers my browser opens pages on when I go to https://www.youtube.com/

 

www.youtube.com 216.58.198.174 
accounts.google.com 216.58.210.45

www.gstatic.com 216.58.198.163 
yt3.ggpht.com 216.58.208.129 

 

When you go to some other sites e.g., newspaper sites etc., the list goes on, and on, and...

 

If you use Chrome, install an extension called IPvFoo and you'll see for yourself how many sites your browser connects to.

 

Regards

Re: Do I have a faulty hub 4?

Thanks imjolly and smf22,

 

I just wondered whether the fast setting might be behind the frequency of disconnects, but will leave that to DLM.

 

The volume of Block events has got much worse since our last helpful exchange SMF22.  The firewall log often reaches its limit with 5/10 minutes!

 

I recognised most of the OUT blocks, but the most recent espiside was from the device IP address and are block going out to some very odd places/sites for example, 188.40.254.145 (hetzner), 107,181,19.70 (lighttower fibre) and 94.46.251.56 (nfsi telecom) which I cannot believe are safe or connected to sites we use.

 

 

PS, when I use YouTube the only out block recorded is to a BT IP address beginning 31.55.162.xx

do you have parental controls active on your account?

Re: Do I have a faulty hub 4?

Sorry of the delay in replying.

 

I do have BT Net Protect enables to avoid changes to the DNS settings.

 

Would this be a possible cause?

 

Thanks,

michael.
