This isn't possible. Unless you are talking about the other wireless router? Because if i disconnect the ethernet cable that goes from the modem to that router... then are you saying you want me to connect that cable modem ethernet cable directly to my laptop?


Because what you are describing... that isn't possible because the router has those 3 ethernet cables stuck in it and one of them include the other router and you cannot pull it out.

Cable Modem-------------RouterA-----------RouterB-------3 used ports & 1 open port


Is this how it is set up ?

What is the make & model of the router ? Who is in charge of maintaining the Apt. building equipment setup ?

Cat6 cable is backward compatible with cat5. Cat6 gives better performance & has double bandwith over cat5.

Router A basically is where most of the ethernet cables are attached to.--- Then there are 4 ethernet cables connected to other things.


One is a red ethernet cable to the modem. Another is router b. Another is my ethernet cable which i use to connect to my laptop for wired connection which doesn't work anymore. Another is this blue ethernet cable that goes upwards somewhere.


Does that make sense?


Yes the last port is the one that is available. The other 3 used ports you cannot pull it out. The ethernet that connects to the cable modem however you can.


TP Link router.


The person who does the showing of apartment and renting she usually have someone come over to take a look at things whenever theres a problem.

Well, I think it should be the Apt. complex that needs to replace the router and the cables. Sounds like a Super Glue prank that is causing NO connections. I have been using Linksys (Cisco) networking products in my systems for 14 years, so that is what I am comfortable with.

Home system >> Cable modem----4 port wire/Wifi Router----100ft cat 5 cable---8 port- Hub/Switch--5 computers
^^-2 wired computers
^^-network printer
^^ WiFi Tivo Box
^^WiFi Laptop
^^Android tablet

Work System >> Cable Modem----4port wired Router---- 16 port wired Hub/switch----3>> 5port wired Hubs
24 wired computers connected to network & a 2x2tb Network Storage device
& 2 network printers.

1. Inform who ever owns the router of your problem. (Management)
2. Leave other peoples routers alone.
3. Ask management if the tech that checks out the system can install your own router for your use only and at what cost to you.
That should solve your problem.

Okay this is very strange. Yesterday i had changed the IP4 properties to

192.168.1.101
255 is that other thing.

It was from youtube video that i found. I did this because i thought this was a way to fix my problem since my 50ft ethernet wire did not work.

So right now i just went there and decide to click on obtain an ip address automatically like it was previously before i input the numbers. Thus just go back to what it was yesterday.

I then put in the short ethernet cable to test it out and yes the wired connection worked as expected.

I then took my 50 ft cat6 ethernet cable and plugged it in... and it worked.

I then went and did this with the router downstairs... my 50 ft ethernet cable worked and i see wired connection.

This doesn't make any sense. Why did it not work yesterday and now it worked today? I didn't do any changes to any settings. All i did was change what i did yesterday that didn't work. So basically me putting in the ethernet cable today is the same as it was yesterday and today right now it worked? I see the wired connection at the moment.

Right now im still unsure because this might work for few day then stop working again. Do you know what kind of strange situation is this? Wired works now but then again im not going to get excited because im not sure few days later suddenly it stop working again.

Then the last 2 lines... i changed it to some other numbers not the ones you wrote down. The last numbers were different.

It was from youtube video.

That did not work. So right now i just went there and decide to click on obtain an ip address automatically like it was previously before i input the own numbers.

I then put in the short ethernet cable to test it out and yes the wired connection worked as expected.

Well i never did any changes to any settings at all yesterday until i saw the 50ft new ethernet cable didn't work. So i made changes to those settings with those numbers and it didn't work.

Also i forgot to mention but the reason i clicked on obtain ip address automatically was because when i first put the short ethernet cable into router from laptop... it didn't work... had the computer logo with the yellow exclamation point with it. This is the same logo i have when my 50ft ethernet cable didnt work.

So i press obtain ip address autoatmically instead and then wired connection worked for short router. But i figure okay try the 50ft long cable and expected it to not work like yesterday... yet it worked.

I honestly dont know why its working now.

I forgot to mention but yesterday I did download a microsoft fix it file where ppl said it would solve this issue. BUt yesterday when i put ethernet cable after doing that, it still didnt work. However... could it be because i had changed the ip address with the ip4 settings with those numbers and thats why?

The only thing i can think of that is the reason it works today with ethernet cable and not yesterday is b/c i downloaded that microsoft fix it file... but i didn't revert those ip4 numbers back to the original obtain ip address automatically...

Depending on how many people are connected to the WiFi and how the two routers are set up (both in the way they connect to each other and how their software is set up), and whether the internet is also being shared unknowingly with the public, will depend on the number of IP Addresses that can be assigned.

If you manually changed the IP address your computer has and it didn't work then you could well have tried to use an IP Address that was already taken by somebody else, or alternatively the router has been set up to give you a fixed IP address & what you set up yourself clashed with what the router wanted you to have so you didn't get a connection.

Obtaining an IP Address automatically is the easiest way to get a connection in your situation, because you (presumably) cannot access the configuration page of either Router A or Router B to see what IP Addresses have been assigned to other people.


A little bit more info on IP Addresses: a lot of home routers are only set to give out 150 IP addresses at any one time, with a maximum of 253 IP addresses at any one time (assuming that 192.168.1.0 is the Default Gateway & 192.168.1.255 is always reserved). While I assume that there are not 253 people in your apartment building all using the same Cable Connection (you would need Google Fibre to actually be able to get a half decent connection in that case), it may be possible that people have multiple devices or that the WiFi is not encrypted (i.e. no password required to access it) and as such anyone walking by outside could then use the same internet connection.

Okay but do you know why my ethernet cable when connected to the router works now as oppose to yesterday?

The only different thing i did was the fix it download i installed. Could that been the reason?
