Network monitor....

[Gollom]

I have an LG Smart TV that is connected via a Cat5E patch cable to a Gigabit hub (that in turn is connected to my router gigabit port via Cat6) and has been for quite some time - TV does not support standard WiFi, but via some madly expensive LG AP USB adaptor. For some reason, it has suddenly decided to constantly disconnect and then reconnect successfully about 80% of the time.

I am pretty sure it is not my router, internet connection or infrastructure (all other things are fine and nothing has changed). I strongly suspect the TV but want to prove it so am looking for a network monitor I could run for a couple of days to see if it is my network that is in fact causing the issue. Most of the stuff I see is Enterprise level and needs licencing. Anybody know of anything suitable?

Ethereal (now known as Wireshark) was always my friend back in the day. It does take some interpreting though.

Set a static IP on the TV and setup a cmd ping to store to a txt file.

Something like

ping -t 192.168.1.1|cmd /q /v /c "(pause&pause)>nul & for /l %a in () do (set /p "data=" && echo(!date! !time! !data!)&ping -n 2 192.168.1.1>nul" >C:\pingtest.txt

You have to run cmd as admin for it to work.

Just an update on this - the gigabit hub it is connected to is known good (it has another device connected which is fine).

So, on the basis that everything is worth a shot I proved good the patch cable - still no joy.

Ran cable to another gigabit hub in the room next door (hope she never finds the hole in the wall.... LOL) and voila it works!!

Just curious as to why that should be - any thoughts? Puzzled!!!

Did it get a new IP address? Is the TV gigabit capable or is it connecting at 100mbit?

For a basic network scanner try Fing on your phone or tablet.

you could also try converting wifi to ethernet with one of these.

Bridge VAP11G-300 Cable Convert RJ45 Ethernet Port to Wireless/WiFi AP Vonets SY 848379473540 | eBay

I use one to enable external access to an old ethernet CCTV, and also my Sky box that didnt have wifi.
