help needed on wire home network

bros and sis..

i have wired my whole house with cat6 lan in all my rooms.
Recently i did a inbuilt tv console in my living room and re-mount all my ac casing and my lan casing in my tv console instead of mounting on the wall.

i have no issue with the connection for all rooms except room 3. the distance of the lan wired from ONT -> router -> room 3 is less than 40m.
for all other rooms, the dl and up speed is 900m+ but my room 3 keep limited to 90m+. prior to installing my tv console, everything is running smoothly. i tried re-wiring the cat6 jack for room 3 data point at both ends and my ethernet connection still shows 100mbps while other room showed 1gbps.

can all kind bros and sis please help?

regards

Could it be your device in room 3 can only support fast ethernet, or maybe its support fast ethernet cos of some factors?

hmmm. i use the same desktop to test for all rooms. meaning i shift the desktop around.

Prior to the installation of the tv console, it was running at 1gbps

but it did not touched the wire that was alr in the casing leh. they only touched the outer where they shift from wall mount to console mount. where i also re-wire the jack. if wire damage, there should be no connectivity instead of just limiting my network at 100mbps ma.

Connect to another LAN Port.
If no available port you may swap to test.
Alternately pull out and reinsert it with a click sound.

One of the 8 wires may b broken so limited ur speed 2 100mbps. I vaguely recall fast Ethernet needs 6 wires only but I may b wrong. U can get a wire tester 2 check also.

Up to 100Mbps need only 2 pairs (pins 1-2-3-6). GBE needs all 4 pairs.

a wire tester can only check whether there is connectivity right? but unable to check whether there is interference or whether all my 8 wires are working correctly?

Rj45 checker can check if all the wires are properly crimped or paired correctly.

Most of the time its due to incorrectly paired keystone or the tip..

Will there still be connection if it was paired incorrectly or i did not crimp well?
cos my ethernet card reflecting orange and red light which indicates interference?

if its not crimped properly, it might work at only 100mbps or doesn't work at all, depending on whether the pair for fast ethernet is crimped properly or not.

LEDs do not reflect interference, it only reflect power/fast or gigabit ethernet.

if its red light, i suspect there is a high chance of crimping error.

renfred89, thank you for this insight. so just re-clarifying. so even if it is not crimped properly, chances are there will still be connectivity by running only at 100mbps. am i right to say that?

whereas, the chances for interference due to near electric cables are quite low?

Yes you are right.

Interference will not drastically reduces the speed to such an extent unless you're saying you're running the Ethernet cable in the same trunk of power cables.. if yes, that's suicide. Lol

hahah. i wont say in the same trunk, but all my cables right now are not covered by any trunking as we modified and mount it on the console. meaning they are pretty near to each other at the back of the console (but i cant see it now)

what are the consequences if it is too near like side by side? will it still drastically reduces the speed and limit the speed to 100mbps?
