OT: Gigabit LAN funny

No. Everything seems to be working as expected. You have two links, not one, and each will negotiate speed independently of any others.

No.

The GS105 and HH3 are operating in store and forward mode. Each link will operate at the maximum it can.

So? Cat5e is perfectly good for 1 gigabit ethernet.

In that case I may as well use the port that is marked 'Gigabit' on the HH3A, and not one of the other three 'ordinary' ports ?.

Quelle surprise. Samsung = s*it.

In practice, it's unlikely to make any difference.

I never understood why they make just one port 1G, and the other 3 all 100M.

On the HH5a (presumably the HH6 too) all four LAN ports and the WAN port are gigabit - can run openWRT/LEDE too (soldered a serial port onto one yesterday for a friend).

I've got three TVs here on the BT home hub all via Wi-Fi, and none drops its connection. And one is a Samsung.

Which "it" is dropping "its" connection?

Samsung drops its Wifi (other Wifi devices stay connected). Home Hub drops WiFi (all HH WiFi devices lose connection). Samsung loses connection to the internet (HH etc still connected to internet). HH etc lose internet connection.

Tellies these days regulary "phone home" looking for firmware updates. Our Panasonic does it just before 0300 every morning. Perhaps part of that is a partial reset causing the TVs WiFi to drop?

Actually it did ! (but only from the visible led aspect).

I moved the downstairs patch cable from the ordinary lan port on the back of the HH3a to the one marked Gigabit, and hey presto, the GS105 port, upstairs at the other end of the cable now illuminates and blinks both green LEDs.

The patch cables at each end are home brew. They are pieces of a

10 metre patch cable bought in a car boot sale and marked :-

"ENHANCED 350Mhz Patch CordE87647-DG AWM 600C 30V , eTL verified to EIA/TIA 568A CAt 5e Draft 8b"

and fitted with Philex cat5e plugs from Maplin and using a proper crimp (and a damn good Draper Lupe to see what Im doing :-) ).

That just leaves the one remaining GS105 port which is connected using a yellow Cat5 patch cable to my Samsung 22H5600 tv. This is still showing one green LED. But it doesn't affect the quality of the stuff that the BFI player allows free access to :-).

This yellow cable is marked :-

"Type CM 24awg 75oC C-UL E-201854-B TIA/EIA 568-8.2 cat5 patch"

I'll try another one (can't remember where this came from) out of interest.

Well maybe, but my faithful old Sony MFM 17 inch LCD TV died just after Christmas and a quick replacement was needed.

It had Picture-in-PIcture, so I could use it as a PC monitor and connect my Humax 9200 to supply the TV picture, plus all the catchup in a window.

Only Samsung seem to make small TV's that have a similar feature, but the TV signal now only comes from the Samsung itself, so the trusty Humax 9200 is either going to be binned or possibly loaded up with a 3rd party Linux distro.

I did consider getting one of those ultra-wide format monitors that a number of people make, but the Humax 9200 does not have an HDMI output, it's either scart or red/yellow/white phono connections which no modern monitor will accept. My old HAzro 24 inch monitor does allow this but even their latest versions don't.

So that left only one possibility, a new IPS monitor and a TV side by side, or stacked vertically on a vesa pole, or a decent IPS monitor and a small broadcast quality monitor to show the TV output from the Humax, since space is an issue.

Unfortunately the latter are pro-jobbies with price tags to match.

So the Samsung is the chosen solution and I have to say I think it is OK. It isn't IPS so you have to be careful with the viewing angle and the football mode is a bit wierd, but once all the as-supplied colour settings are re-done properly it is a really nice little TV.

Perhaps you have issues with their larger TV's. I can't comment really.

Make sure it has all 8 pins wired. Some el-cheapo patch leads only have

4 wires. It'll be obvious if you look at the plugs. Those cables will do a maximum of 100Mbit only.

My Humax HD FOX T2 seemed to do that at 4 AM and no way of stopping it apart from unplugging the lan cable, which I have now done.

Here is a section of the event log on the HH3a.

Something happened at 07:13 when only the HH3a was on and connected. All my PC and TV stuff is switched off, or not connected to the LAN (Humax HD Fox t2).

PPP LCP Send Termination Request [User request]

And lots and lots of invalid packet messages.

The BT community forum has a several threads from users who have this behaviour. some get it several times a day, I get it every couple of days or so. I might get Openreach out to install a proper NTE5 so I can easily isolate my phone extension. Apparently the wire from pin 3? is obsolete these days.

Do you actually expect a TV to have a gigabit port?

If you install the hacked firmware, thdere's an option in the web interface to stop that update.

Who knows these days? it might actually be cheaper to fit a gig chip from the likes of Realtek than a 100Mbit from, say, Intel.
