I got this modem from a friend, a Huawei HG530u
its a ADSL modem and I have a Internet connection over Ethernet
I knew this was going to be difficult but I managed somehow to put the Internet connection in LAN1 and I can share it over wireless, phone and laptop have Internet,no problem there
but I also have a desktop PC, which can access the modem configuration but nothing more (over LAN port),
so I tried to copy IP and gateway and other settings from my mobile devices and I managed to lose connection on my laptop, but I regained it somehow (truly by accident)

So... what should I do, what info do you need to help me and do you also think this is a really stupid situation >D

Oh yeah, I tried with enabled and disabled DHCP on this modem, nothing is changing.

Also, I know buying a router would have been smarter but this was the cheapest option for me so I'm gonna have lots of fun in the next couple of days :p

Not a stupid situation at all. No harm in trying things out to save some money. And networking can get tricky...

This link will help:

http://setuprouter.com/router/huawei/hg530/manual-157.pdf

The manual will help because you will be able to check that your physical connections and corresponding configurations are as they should be for your network. Plus tell you about the indicator lights,what they mean, and any troubleshooting you can do. Very useful information.

Many factors involved so work through the manual to verify what you have done and correct if and as necessary.

Are you sure that the modem ifully functional. I am not one to look the proverbial "gift horse" in the mouth but you do not need to struggle with something that is not workable to begin with.

Do suggest that you write down some notes as your work and test. Start simple and change only one thing at a time. Sketch out a simple diagram of your network to keep track of the bigger picture.

Good news is that it appears that you have gotten it all to work to some extent. Just be methodical and work down to some specific problem.

You will know much more by then and be able to explain what you have done, what happened (or did not happen), and then understand suggestions for possible fixes.

Thank you Ralston18, I never thought about reading the manual lol
it didn't help me much but I appreciate any help I can get.

The thing is this ADSL modem cant be used as a regular router as it seems I tried many IP submask and gateway configurations, it just wont share ineteret over LAN2,3 and 4, but every port allows access to the configuration page of the modem.

I did manage just 5 minutes ago, to get internet on all my devices, thankfully my desktop PC has 2 ethernet ports so I set it up like this:
ISP>Desktop PC>ADSLmodem>wireless devices

But this isn't a real solution since my desktop PC needs to be on all the time for my other devices to have internet.
Or I have to switch cables every time I turn my PC off or on.

Probably not a viable setup. Two active/enabled network adapters on one device is doable but intended for special situations such as bridging.

Look at Page 4 in the manual. That is how the physical connections need to be.

See Pages 13-16 to reset to factory settings and basically "re-do" the configuration.

Get this to work:

Wall jack -------telephone line ------>ADSL Modem [WAN port]

And ADSL Modem [LAN port 1] -------ethernet cable ------> to one of the computer's network adapters. Enable that adapter and disable the other.

After factory reset, the modem should be set at 192.168.1.1 with a subnet mask of 255.255.255.0

All of your devices will use the same subnet mask (255.255.255.0).

You will configure your computer's enabled network adapter to get its IP address via DHCP by using IP 192.168.1.1 (DHCP Server) as the source.

Wireless devices will be configured in the same manner - all must look to 192.168.1.1 (DHCP Server) to get their IP address and must also have the necessary SSID, encryption, and password to wirelessly join the network.

Please use the manual to guide yourself through the network setup/configuration process. And pay attention to the indicator lights. Sometimes each step of the process takes time and you have to watch the indicator lights to know that the process has completed and then you can proceed to the next step. Or see if some error has occured.

And yes, all devices will be able to access the modem's configuration pages. You prevent other devices from accessing the configuration pages by changing the modem/router's user name (default is admin) and password (default is admin).

I did it, I was told to set the primary dns to 8.8.8.8, but this was wrong, so wrong, it should be the ISP's IP with only the last numbers changed to 255.
Like this
xxx.xxx.xxx.255
and that was it

Thanks Ralston18 for giving me ideas to try, and thanks to tomshardware for this awesome community.

So how can I close this thread now?
Maybe it'll close automatically or a mod can close this :D

I am a bit leery about the use of the IP address ending in 255.

That is a broadcast IP and there may be other consequences of using it.

Suggest that you at least do a google search using words such as "using IP address ending in 255".

If something strange starts happening the additional insight and information may help you identify the problem.

Thanks, I searched the web as you suggested, perhaps I did not find the same results as you did, but I don't see a problem with my current setup, since the .255 IP is only for my PC to the modem, and I'm only using this network for my own devices and only for internet, no device sharing whatsoever, the modem still uses the ISP's IP to connect to the internet.

Thank You
that article was great, I'm gonna stick with this setup since I'm located in a area where I only have one neighbor who, if he would want to try to connect to my wi-fi would have to get in my house, since its weak and he is no computer pro to hack into my network so security is not an issue, and "The choice of IP address does not affect your network performance in any meaningful way." was the last line that linked website mentioned at the end of the article. But if I lived in the city with like 100 mobile devices in range, I would change my IP to a more secure one. Just one more thing, do you think my setup would also work if I had a 0 instead of 255 at the end of my DNS IP?

Ending with a "0" (zero) is reserved (per the link) for network protocols.

Even though you may be able to use "0" and have things work you should stay within accepted practices.

Here are a couple of reasons why: 1) The rules provide a common reference so "0" can be used as it currently is without any possible conflicts. 2) There may be some future network standard that takes advantage of "0" not being on the end of an IP. Or being on the end in places where it is permitted. If you put a "0", either way, at the end of an IP address then you may have some conflict(s) within the network. If not immediately, then later.

Tinkering around with IP addresses can be interesting. And controlling, blocking, limiting IP addresses is a component of network security. However, if you stray from the rules you may inadvertently create a vulnerability making your network less secure.

And I would hope that someone else will add in additional "cautions" based on their knowledge and experience.
