I've tried quite a few of these but some others in there I'll try tonight.
I've just found out when eBay would not work on wife's phone via WiFi.... The eBay app would load but wouldn't load the sujested items page but searching for stuff and her watched list actually loaded :/
The thing that's bugging me from a fault diagnosis point is everything was working for 3 days then started with these issues with no changes to pfsense or network set up -
If thats a cable modem I bet its a Puma 6 equipped model being a Virgin Superhub 3 en all... Reason I state that is that Puma 6 modems can have issues with UDP connections which DNS queries are..
But- Look at Status / Services on your box and see if everything is running.
-
@chpalmer yes i think the "SuperHub3" does indeed have the intel Puma 6 chip-set which has known issues.
i will be putting the PFsense box back into the loop tonight and running some more tests.the bit that really annoys me is that there is no consistency, some websites would not load on some devices but would work no problems on others.
ill report back with anything i can find during tonight's testing. fingers crossed
-
@chpalmer ![alt text] not sure what services should be running but this is the page, everything seems to be running ok?
-
@grimson just booted up my pfsense machine, put superhub back into modem mode, and plugged it all back as origionally. and ive hit the same issues
ive run through both of those links and cant find anything out of the ordinary. -
i cant see anything out of the ordinary in the firewall logs when trying to access ebay/virgintvgo/websites that wont load.
im beginning to wonder if this is even a pfsense issue? surely if something was being blocked it should be blocked on all devices?
is there any logs or screenshots i can post up that would help rule anything out??
-
This may seem like a bizarre request, but would you please check and report the MTU of your WAN interface? If your WAN MTU is 576 it would explain the odd behavior you describe. There is a fix in the install guide for 2.4.4.
-
@bfeitell both wan and Lan are saying MTU 1500
They are both via the same NIC vlan'd as I've only got 1 NIC with no room for expansion (thin client) -
Which thinclient? Is there room for a half card?
-
@chpalmer it's a "10zig" 58xx model.
I have got several usb to ethernet adapters (please don't shoot me) I did have great success with one.... But it was limiting my download to 60mbps so I went for vlan's
My only other option is to get a mini pcie ethernet card (one with a small board and cable leading to rj45 port on another small board and try to butcher the case. Don't want to go down that route really.
Vlan's should work fine. My internet is only 200/12mbps down/up so shouldn't be limited but a vlan.... Speed tests all indicate I'm getting 200-220 down and 12-13up.
It's just a few pesky issues :( -
@noob said in Odd behaviour!:
10zig" 58xx
This guy? https://www.parkytowers.me.uk/thin/10zig/58xx/index.shtml
Try this program.. https://www.grc.com/dns/benchmark.htm
-
@chpalmer that's the puppy! Was a 99p bargain on eBay. Was planning on using it for the kids of CCTV station. But I'm still saving up for the HIKvision IP cameras and the kids well they are not allowed in my office so screw em lol
I'll try that DNS tester. Any results I should be looking out for or will they jump out at me if there is an issue? -
Maybe a mini pci to ethernet solution??

The dns program will show if your DNS queries are having issues. Ill see if I can find some documentation on what to look for..

from what i can make out.... DNS tester above results..
the bad:
System has only ONE (router based) nameserver configured.
the good:
System's sole nameserver is alive and replying to queries.
System nameserver is faster than ALL public alternatives.
This system's nameserver is 100% reliable.
This system nameserver returns errors.
System nameserver is replying to all query types.just for giggles i did the DNS "spoofability" test too:
Anti-Spoofing Safety: Excellent
External Ping: ignored (Nice, as it's preferable for it to be less visible.)
External Query: ignored (This means the nameserver is more spoof resistant.)
DNSSEC Security: supported (This server supports improved security standards.)
Alphabetic Case: all lower (An improvement could be created by mixing case.)
Extra Anti-Spoofing: unknown (Unable to obtain server fingerprint.)the only thing i can see thats wrong is the DNS benchmark tester only round 192.168.1.1 (my pfsence lan ip, default setting) as my only dns resolver..... but in pfsense it has automatically added
127.0.0.1(for loop back?)
194.168.4.100
194.168.8.100
these 2 194 addresses are NTL/Virgin Media's DNS servers -
@chpalmer as i am behind pfsense its showing uncached as 100% where as from that link above should ready 91-99% as the VM hub has a puma chipset.
other than that it all looks fine to me :/
I'm not convinced paying £30+ for a mini pcie to ethernet adapter is going to fix this issue.... Vlan's should work
-
having looked through millions of google/forum pages i came across on that wanted to look at this graph
ive not experienced any outages and everything seems to load so im not really sure how to take this info, any ideas?when i try to upload image like i did yestoday i get "Something went wrong while parsing server response"
-
anyone got any further ideas??
as soon as i take the PFsense box out of the loop everything works fine with no issues. put PFsense back in and i get the same issues,
is there any "logging" i can turn on or post that would help with a diagnosis? -
