That's very few informations.
What kind of cable? LAN? Serial? Fibre? 😉
Is the 486 connected to your router via a LAN cable or to your Win8 machine?
From the look from the screenshot your Win8 machine is configured to get its IP from a router via DHCP.
which means PCs will get automatically an IP and the settings from the router.(If your windows is configured to use DHCP)
That should work in Win95 the same.

yes.. as you write..

windows 8 on that pc.. router via lan cable..
i tryed setup DNS like on screenshot, but not working

So the 486 has a LAN Card and is connected to your router.
The drivers are correctly installed and you can setup the the card properly?
Under the TCP/IP settings you turned off DHCP and manually set the IP, gateway and DNS adress?
I can't really remember how networking under 95 worked since i didn't really used 95 since al least 10 years.
Possible you have to activate TCPIP first or something like that perhaps someone can jump in and back my memory. 😁

correct..
DHCP turned off, IP: 91.148.27.177, gateway 192.168.1.1, dns: 192.168.1.1

not working

Ahh, there is your Problem.
set the IP to 192.168.1.2 i hope this IP isn't used from another Net Device.

I suggest using a fixed IP. For simple networks like that DHCP is just a headache.
For browsers Opera is one of the best for old machines. They supported
486 instructions very very late.

For Windows 3.1/3.11: Opera 3.60
For Windows 95 on a 486-25 to 486-40: Opera 4
For Windows 95 on a 486-50 to 486-75: Opera 6 or maybe Opera 8.5
For Windows 95 on a 486-100 or faster: Opera 8.5
For Windows 98 on a 486-100 or faster: Opera 9.6 (that's what I am using)

Make sure you have enough RAM. 32 MB+

first i must run network..

PING have not respons..

Firewalls may prevent pings.

HMM, now i can ping DNS 91...
but i cant open www page 😒
ping 192.168.1.1 doesnt work.. (access to my modem setup)

That's strange but you have 2 other DNS server on your Win8 config.
Perhaps your router can't handle DNS requests or it's wrong configured.
try to give Win95 also the othe 2 DNS server. (217.119.113.244 and 8.8.4.4)
Also you can try 8.8.8.8 that's a free DNS server from Google.
Also you can try to ping 8.8.8.8 if it pings you have a DNS problem.

not working..

if i plug cable 2 to my 8bit atari 800xe/xl and run auto IP config software, result is different..

That's normal!
The IP Adress can only exist once in a network.
Your Router is giving every computer a unique adress via DHCP in a configured number space.
It looks like your routers DHCP is configured to use 192.168.1.100-192.168.1.1xx <i can't say, till what number your router is configured but <255
you are in a Class C privat network, which means your net can have a maximum of 254 devices in the same net.
1st Device is your router 192.168.1.1 and the other devices you might adress yourself via the net config or DHCP.
All you have to look for is that you don't assign an IP adress twice or more.
For example, don't assign adresses manually that are configed in the DHCP pool.
Go for numbers outside of the pool.(you might look up the pool in your router config.)
And don't assign the IP 192.168.1.0 or 255. 0 is just indicating the net name and 255 is exclusive for broadcast traffic.

As your just starting out, I would set the PC to get an address from DHCP like the Atari, If the PC still doesn't get an address then you know the problem with TCP on that PC. This link will show you how
http://www2.slac.stanford.edu/comp/net/dhcp/windows95.htm

In the Start/Run box type Winipcfg This will show your IP address
If you do get an IP (It should be something like 192.168.1.?) then try to ping google. If you can then great if not check your DNS server, these should be the same as your Windows 8 PC

The internet Explorer that comes with Win95 is pretty useless now, but it should at least start to load the MSN homepage if your online

tried..not working.. 😒

Make sure you set DNS to your routers gateway and give it some dumb domain name. I just name it my router.
Win9x never wants to work if I don't set it, even when it shouldn't need it.

Basically
Under Network Properties TCP/IP
DNS CONFIGURATION:
Enable DNS:
Host - Whatever Domain- Whatever
Dns Server Search Data - Add 192.168.1.1 (whatever your routers gateway is)

Gateway:
Add - Whatever your routers gateway is

WINS CONFIG: Ignore\Disable

IP Address:
Specify an IP address: (even if your router is using DHCP)
IP Address: 192.168.1.whatever (2-254)
Subnetmask: 255.255.255.0

It should work then after a reboot.

Set everything to "auto" and tell us what settings you get in "winipcfg"?

I see no point in manually setting the address when he has a working dhcp server. You just confuse him.

that's right... if this guy can't tell basic networking from his ass, just use DHCP and be done with it.... it will work and work good enough! he will have intarwebs!

wow 😀
i replace network card - 3CSOHO100B-TX

and.....works 😀
thanks guys 😀
