This Router/Modem issue has me stumped...

[stilly]

Well, Kinda.

I have (for this story) two computers. Computer A and Computer B.

Computer A is MY computer and MY computer sits in the room and WAS plugged into the router (which plugs into the modem). Computer B sits in a room down the hall and plugs into the wall, then the wall jack goes to a jack in my room and a cable comes out and plugs into a switch and then the switch plugs into the router.

There are four ports on the router. ONE port is being used by the cable from the switch, one port WAS being used by MY computer (Computer A) and one port is being used by the printer and one by my game machine.

Something happened last night and the WIFI was lost, I was told that the WIFI was spotty and kept going in and out, so I power cycled the router. I said to use the computer then if wifi sucks and she got on the computer but she had no internet access.

She had an address issued by the router, 10.0.0.102 but no internet access. She could PING the router, but could not ping onto the internet. There was no WIFI and I see the WIFI light is blinking slowly.

OH DAMN. I just typed IPCONFIG on my computer and see that the internet is the same address okak. Nevermind. I see the issue here. The issue is that this damn thing is busted. Time for a new router. The router has a passthrough and it is giving MY computer access, but not hers, it is NOT performing DHCP. ****ing router...

okay nevermind. This has been solved.

Why not just manually set the network settings on the client if DHCP leases aren't being handed out?

How? AS in static IP addresses? I always thought that the router HAD to issue the dhcp address, you know- you use ITS address IT gives you to access the internets. But the address you use to get onto the internets is a different address. I never really thought of that. See? One of those things I missed by not getting certified and spending all that cash for tests and classes...

But it IS called a gateway for that reason. I never really thought of it because in the past everything just worked.

I will give computer B a static ip address to match the 10 network and I will move mine to static as well and as long as we have the gateway it will hopefully perform its duties.

Of course the WIFI is also not working, even though it says it is in the setup. I have more time, I will have a look at that.

Thank you for the idea.


** Update**
And it appears that it works, so the NAT is functional. Now I just need to hook up my POE wap, program it and I should be good to go. I think.

The router is essentially a single port router now, I do not know what happened to it, but it has taken a hit and hates life.

I will leave the DHCP alone I guess for wifi anyways.

I would factory reset and use wpa2/aes. Don't know the router but 10.0.0.102 seems like a weird/high range IP address you are getting nat'd from the router. You can check DHCP config on the router and see if that is the range. If you are having problems connecting to your other computer turn off encryption and see if it works. If it does than maybe update the wifi card/driver on the computer in question. I would just go DHCP on everything since you have a small network but if you don't want to once a device gets an ip usually you can reserve the ip for that device (mac address)

[CaMakarovnik]

10.0.0.102 is a class A private subnet address (the class C 192.168.x.x is more common, but not better). NAT will work fine with a class A address.

[stilly]

Everything was FINE. Nothing was wrong, then one day- Hey no WIFI! It said CONNECTED but gave her no internet access.

So I power cycled the modem since computer B ALSO has no internet access...

The router is a WIR-615.

DHCP was set to give us addresses from 10.0.0.5 to 10.0.0.20.

WPA personal was selected with AES

There was NOTHING WRONG.

But the damn router just decided to stop sharing the internet connection. It only gave Computer A the internet connection (because of the address?) and the address was the one given to the router from the isp.

SO, this router is jacked. Time for a new one, but my moving everyone to static, now we all have our own IP address that I programmed, even her cell phone now has a static ip address and access is no longer an issue.


And I have three NR041 routers coming my way now because I shotgun bid and got them for cheap. I will program them and store them.

Heh. I just wish I knew what the hell was wrong with this damn router. It broke like that personal firewall program kerio used to break. Working fine till it decides to snap and go ASH and kill the connection...

There is possibility that your provider doesn't release the IP quickly when you swap devices. My previous DSL provider took like three hours to release the IP number. So, when I went from one computer plugged in, to a router, with multiple computers behind it, I had no internet service. The solution was to unplug everything and wait.

Do you mean you have a DIR-615?

Maybe just flash the firmware to dd-wrt will fix the problem..along with just having better firmware.

Holy ****. Montu thanks. You JUST reminded me why I even bought this stupid router in the first place, even though there was a busted wifi antenna (cracked on the hinge, just lays there limp now) I got this thing for $20 and I was gonna DDWRT it. I just forgot to do that by the time I needed it and installed it and all.

Heh, I should check my Netopias as well. I wonder if I bought them with the idea of flashing them too.

I tend to lurk at night and become a different beast. I will buy the stupidest things on ebay with some idea of performing some miraculous event (or something) with them. Then when they arrive later on I am scratching my head as to why I bought it...


As for ISP slow to release IP address. Hmm, no, Can't say that DSLEXTREME does that, but I will say that it was not an issue since even after letting it sit for a day later It still refused to give up any access to DHCP users.

It is like the router is saying- you can have DHCP IP address OR you can have internet access for everyone, but you can NOT have both. So take your pick...

bah. I will setup the other NR041s and then flash this bad boy.

[uparmor]

You are most likely in 2 different subnets. One is a 192.xxxxx the other is 10.xxxxx. Unless you do some fancy stuff they wont talk. Switch the 10 to a 192

[catmman]

Yeah but for the 10. address they said it was issued by the router so I assume it was nat'd.
