Is it possible to make wifi router with openWRT to be like an computer ? I mean, that admin of network (where wifi is connected) couldn't recognize, that any wifi router is connected.
1) Increase TTL of forwarded packets using iptables.
2) Change WAN MAC to MAC of PC's copper NIC.
3) Do not publish services on WAN.

Here's the situation...
I have 3 desktop Win PC's ("A", "B" and "C") connected to a Switch (TP-Link 8 Gigaport Switch). Also connected to my switch is the cable company's router, and I have a 100 foot Ethernet wire to the middle of my house where there is a wireless router.
This works great - home automation stuff + cell phone connect to wireless router, A, B, & C can talk to each other (share files, remote desktop, shared printer, etc). Life was grand.
Then I bought a MS Surface. I can't get the Surface to "see" A, B & C, and they can't see the Surface. I assume it is because the wireless router OR the Switch won't share outside their walls. How do I do that?
I'm a programmer, not a network guy (obviously) so dumb it down for me! Thanks!
I'll assume broadcasts or multicasts are used to "see" other hosts.
If your wireless router is configured in NAT mode then broadcasts won't be forwarded between your wired and wireless network.
Try configuring your wireless router to operate in bridged mode which will allow broadcasts to be forwarded between the wired and wireless networks. This will allow discovery to "see" hosts on the other part of the network.
As your cable router will be acting as a DHCP server you should disable the DHCP server on you wireless router when it is operating in bridged mode.
I have the following scenario.
I have a laptop with wifi internet . I connected my laptop to Netgear router via ethernet cable.
I want to get the laptop wifi internet to be shared with those who connect to router.
Is it possible.
First of all, rather than using a router (Netgear router), you should have used switch.
Now, since you have used a router, you have to write a static route in your netgear router which would say 0.0.0.0 0.0.0.0 (a packet heading towards internet) have to go to the IP address which is configured on the interface of your laptop where you have plugged Ethernet cable.

I can't send pdu from pc to wireless laptop
It actually can send the PDU because u only have a network so the network between your PCs and your laptops is actually the same network. Check your IP address on your PC (it should be on the same network / subnet). If your PCs and laptops are already on the same subnet, check the port of the connected cable on the wireless router. It should be placed on ethernet / gigaethernet. But u can't connect it into internet port.
The wireless router that u are using is actually only Access Point. Because of that, it only can have a single network either on LAN or wireless.
Hope it helps!
Recently I have followed this link to setup a wireless router into an access point in my home.
Our current network components are as follows:
Main router (192.168.1.1): a Sercomm router configured by the ISP, with DHCP enabled for address 192.168.1.30 onwards.
AP router (192.168.1.2): a TP-Link WD8970 router on the bridge mode, with WDS turned on (on the same SSID, mode and channel as the main router) and DHCP turned off. However, this AP is configured to broadcast a different SSID to indicate a different storey.
Devices (182.168.1.xx): desktop or mobile clients that could connect to both SSIDs.
(click here for the topology image)
The problem is that:
Most of the time, devices connected to AP router's SSID is given 169.254.x.x IP addresses and could not reach the internet
Devices that is configured with a dynamic IP and connected to the main router's SSID could reach only devices connected to the main router's SSID
Devices that is configured with a static IP and connected to AP router's SSID could reach both routers (the main router at 192.168.1.1 and the AP router at 192.168.1.2, respectively)
DHCP packets are not forwarded from the main router (192.168.1.1) to the AP router (192.168.1.2), while other types of packets could flow through
How would you advice on configuring this home network differently, to make it more stable and usable?
I had the same issues in past days. I fixed checking the flag "DHCP RELAY". As soon as I checked it all went fine. All devices connected to the wireless router have received the IP address form DHCP server.
https://www.tp-link.com/us/support/faq/1630/ (the real configuration page on Archer D7 is slightly different form what stated in the link).
This was my network: I have a small usb powered 4G modem/router connected to internet. I wanted to share the internet with several devices located far from the 4G modem/router, so I decided to extend the coverage by means a TP-LINK Archer D7 ADSL modem/router used as Wifi access point. I connected the 4G modem to AP through WDS. The pc's and printers connected to Archer D7 (AP) were fine, security camera, smartphones etc.. no IP from DHCP. After the setting DHCP RELAY everything went fine.
Most of the time, devices connected to AP router's SSID is given 169.254.x.x IP addresses and could not reach the internet
This issue has to do with the WDS connection and poor connection from the AP to the main router. As a wifi expert (ok, expired CWNA) it's never a good idea to use WiFi extenders or WDS in your case. It increases interference, adds an extra hope, and rarely helps. While it's easy to think of these as a signal booster the wifi network protocol isn't setup for these types of connections. Only some commercial APs with parabolic antennas can truly benefit from wifi extenders.
Test with a cable connected from the main router to the AP and use the interfaces instead of wifi. It's possible you have DHCP issues with your wifi issue so first test with static IPs.
If this works then you should leave the cable in place. Understandably this isn't always possible so replacing your main router with a quality wifi router would be my 2nd choice. Sorry I don't know any good consumer grade APs but they are out there.
I have a PC (Windows 10) connected to my router through an ethernet cable. I also have a few devices connected to the same router. What I would like to do is make them "see" each other. I want to transfer files from my phone to my pc and back using ES File Explorer. I want to Broadcast movies to my smart TV using apps like Wondershare.
My PC is visible for other devices but I can't seem to find it using my TV or phone. Therefore... i guess all these devices are not connected to the same "mini-network". I don't know how to call it.
What should I do?
If you are in the same subnet as the router and there are no firewall rules blocking it, you should be able to see the devices on your computer. If you go to your phone settings, search for the IP and try to ping it with the command line of your choice. If it does not work, compare the subnet mask and ip address of your devices, make sure they are in the same subnet.
On windows the command is: ipconfig on linux: ifconfig or the new form: ip addr
