very peculiar problem with v-fiber and edgerouter x

i have the airtel router placed on ground floor from where i have an ethernet cable coming to the basement where edgerouter is placed.

this cable connected directly to my pc gives me proper download speeds of around 40mbps. but upload speeds are shite at 0.2mbps.

the same cable when connected to edgerouter x... speeds on my pc... are basically reversed. downloads are .4mbps but uploads are fine at 8-9mbps.

i even ended up installing ddwrt on the edgerouter trying to fix this issue. but exactly the same behavior.

ethernet cable is not old. and connectors seem to be fine.

i cannot think of anything that could be causing this. anyone can think of anything? 😀



i am thinking of replacing the connectors. i personally suck at it so would have to find someone.
replacing ethernet cable so soon seems kind of pointless. might get airtel wiring switched to basement instead.

in VDSL Up Load speeds should Bee Around 10Mbps
about Your Problem I do not think of any solution

Just to rule out the cable, how about taking the edge router to the ground floor temporarily and try with a different shorter ethernet cable?

Was this working before or is this something new being setup?

I think its a cable problem, re-terminate the connectors or as @varkey suggested use a new shorter ethernet cable.

You will be surprised how much RF interference ethernet cables experience especially over long runs >10 meters and unshielded when they act like RF antennas. I assume the cable is routed internally i.e. within the house and no runs are exposed to the environment or near a window. When I had my home wired with D-Link Cat 6 in 2011 I made sure the run was internal to minimise transmission problems and installed in plastic conduit/casing. Works like a charm even 9 years later.

If you experience better performance with a shorter cable just change the cable with DLink, Finolex or other good brand CAT6 or 7. Amazon has unterminated bulk cables on offer plus long pre-terminated "patch" cables of 10+ meters Amazon Basics 15 mt. CAT6

I do not suspect the cable to be an issue given the symptoms you are experiencing, but the proper installation of connectors are basic requirements.

1. I think you are running dual NAT, airtel modem seems to be in router mode, it's best to keep it in bridge mode and then let the ER-X route.
2. Are you running any traffic shaper on the ER-X ?

I love ER-X, and have plenty of clients on the same, EdgeOS works fantastically, never found the need to run ddwrt.

hmm. i do not have any ethernet device at the moment to check edgerouter on groundfloor with shorter wiring.
i suck at installing rj45 so replacing them is kind of complicated. i have tried getting airtel guy to come but he is quite busy this week.
i have considered switching airtel router to bridge mode but i kind of want it's wifi to remain enabled.
er-x has fresh install of openwrt (not ddwrt 😛) and simple configuration. it is configured on failover.
wire is around 25 meters and most of it is outside my house in sunlight. but it is covered with those plastic strips. it is fairly new so it should not be damaged.

i am now considering getting airtel to the basement. and once the speeds through router are good. drag ethernet cable from basement to the room where i need it for cctv connectivity. using Amazon cable instead of D-Link one.

would have to drag a rj11 cable as well because landline is needed on groundfloor and not basement.

what mess.

can anyone tell me if it is possible to run a shitty cctv box with a wireless dongle? 😛 this whole issue is because of the cctv box. otherwise entire house has good wifi coverage with two wireless routers on groundfloor both connected with ethernet cable from basement. and these cables are installed on the same route exposed outside the house and are much older than the airtel cable which is giving me the problem. and i did not even get a cheap cable. got the shielded one that costed around 20 bucks per meter iirc.

I would highly recommend getting EZ Connector for RJ-45 , it makes crimping much easier, I haven't had a single failed crimp because of it. This is the particular one I purchased.

So I need their crimping tool as well? 🤔

nope, you can just use scissors to cut off excess and pull the cable out a few millmeters so that there is no excess wire outside the connector

just did the worst crimping of my life lol. would try to get excitel guy to recrimp. connection totally down now 😀

actually, crimping a RJ45 male plug onto a solid core conductor is against the standards, and is a bad practice. The teeth in the RJ45 male jacks never pierces the solid core and gets seated on the sides leading to loose contacts. I would have terminated the solid core in two ways:

1. Use a RJ45 female socket, and terminate the cable onto the IDC connectors (google the term for clarification), then use a factory made RJ45-RJ45 p/cord from this socket to the equipment.

2. Use a field termination RJ45 male jack, this is a new technology and you may not find it for purchase online. Here the RJ45 male jack has a IDC connector and one can terminate the cable onto the same (not crimp). Check this datasheet http://bit.ly/3bywNGi . It comes in toolless variety too.

Best brands are Commscope, RnM, Molex, Belden. I guess you will not find any of these brands available online. If you decide to go the proper way, and need my help to procure any of them, let me know.

so... it was indeed a crimping issue. got crimping done in the morning. and then found out that airtel was down. airtel guy just left after fixing. turns out airtel did not process my static ip removal request which led to downtime. now i have to reapply for static ip removal. and internet would go down again lol.
