What has happened!

[Demonstroke]

oh man, i have no idea where to even start. I got home today to notice my internet was not working in my room. So i checked the front room and my internet wasn't working their either. I called some friends and they said they were having problems as well. So i called my ISP and they got it working. I checked google only when i did this though.Now the problems start!

I decided to remove the router out of the equation and just use a landline ethernet cable. So i connected my modem directly into my PC in the front room and it could only visit google and wikipedia. Then i connected it to the PC in my room and i can surf the web. This is really frustrating and i think it was a software issue, but it can't be in any way! also my router which i had, now if i plug it into any computers, the lights flash, then all light up, then it resets itself. Its like stuck in a loop rebooting itself. the PC in the front room can even ping all websites just not visit them!

I have no idea what to do !:curse::curse::curse:

Also; when i do any Ipconfig on the front computer it gives me a "?" after IP address:

update:
Tried Winsock XP fix. didnt work.

So you are trying to revert back to the way your network was originally set up, since your ISP fixed the connection issue?

Connect the modem to the ISP's drop in your house (like you had it to begin with). Connect the modem to the router. Then connect each PC to the router; don't use any port labeled 'uplink' if there is one.

If you had to change anything on the PCs in order to connect directly through the modem (without the router), under Control Panel -> Network Connections -> LAN properties -> click TCP/IP and select properties -> make sure all the PCs are set to "obtain an ip address automatically" and "obtain dns automatically".

my router just keeps dropping all the PC's on all ports. But here is what i did and i can now get the first PC (which originally couldn't get on the internet) online.

I completely unplugged and reset the power to the computer, rebooted once after a cold boot. Seemed to fix it but i have a second Ip address listed under ipconfig with a ? next to it. Here is what i mean:

its a DNS problem i believe....maybe ask the ISP to check up the dns because that's the problem sometime....the router is looping or what not because its trying to retreive dns queries from ISP....that's the reason why in the first place you are unable to resolve or sort of resolve FQDN so i think i would give the ISP and ask them to flush out the DNS or i think you should try flush out on your router

How does this explain the fact that i can plug my computer in the back room directly into the modem and connect fine? should i run a ipconfig from there and see if it returns the same information?

[freakinprince]

yeah give it another shot..it possible there was delay and now everything is back in working manners....give another ipconfig a try and post back what you see

try the ipconfig /all command

when you are connected directly to the modem does all computer respond fine? or what?

i re-read your post and you took out the router of the equation..it seems like maybe its your fault at fault after your ISP fixed the connection...so it might be the time to get a new router if you can

[Demonstroke]

These are at both PC's with no router plugged in, modem connection only. Im beginning to suspect your-55e.... needs a new network card (was using onboard)

second PC is running vista so it might provide more data.

Meanwhile, im gonna contact the vendor for my router and find out why its stuck in a constant loop even when running with no modem connected.

[freakinprince]

have you tried resetting the router and doing the power cycle?

is the light showing off in your first computer? is it just stuck at amber light or what?
look at it the physical stuff and maybe you can decide if its going to be a new NIC or not...

it could be the NIC itself as its not providing a whole lot of info ....plus the tunnel is all FFFs? werid

[Demonstroke]

well, thats all the info above i can give as far as actual modem connection goes.As for router, i am positive its a hardware issue. id hate to accept that my NIC and router died in the same day but you never know. The routers reset button which i have tried hitting numerous times does not work at all. I have connected the router just into a PC with no modem conection on it and it does this:

Green power light on
Flashing light for Computer connection, activity
flashes even more
all lights except power go green
all lights except power go off, and a notification for little or no connectivity pops up in my taskbar.
loops above endlessly.

I cannot access my router via Firefox or internet explorer using 192.168.0.1 like i always did. =[ it does the same thing with modem connected to router as well.
-------------
Edit:

I think my NIC might be fine. I have narrowed down the possibility to that my ISP had problems that night, and in an effort to fix what i thought was an issue i could have caused my own router to paperweight. I still have no idea how it happened but my front PC is functioning fine with the modem. This is very strange but ive mailed Dlink about their router lockup, its not a year old i think so i might be able to get a new one.

Sound reasonable?

[Met44]

For one, your first IPCONFIG on this thread shows that the router is propagating the IP address it should be keeping for its WAN interface. It sounds like there was also some DNS issue going on as freakinprince suggested. After we can get private addresses on all your computers the DNS may be the next issue. I read your posts again and it sounded like you still had the router connected at this point. Is that correct?

Ethernet adapter Local Area Connection 3:

IP Address. . . . . . . . . . . . : 68.189.42.33

If so, it follows that if you plug more than one computer in to the router, only the one which received the WAN address will be able to communicate.

You MUST have a modem attached before the router, or the router will not be able to communicate to your ISP.

Can you access the router through 192.168.1.1 (instead of 192.168.0.1)? If you can, we can check some settings there.

[freakinprince]

default for dlink access router is 192.168.0.1 so he was right spot on that...

have you tried release ip (ipconfig /release) then renew it (ipconfig /renew) with the modem attached to the computer?

My brain is still on the DNS issue for you.... there got to be a way where you can flush out the dns off from your computer and allow it to fetch new and write it in a table in the computer for you...

he following article explains how to flush a computer's DNS cache. When a computer visits a website for the first time, it stores the website's DNS information in cache. The next time the computer visits a website, it looks in the cache to see if the website's information is present to use. This can cause problems if the website's DNS information has changed since the computer's last visit. Flushing the cache removes all the information stored in cache, forcing the computer to find the new DNS information for the website.

so try this ...hopefully it will work...but at least it will eliminate dns from your computer if possible

ipconfig /flushdns

this is something i would try

[Demonstroke]

it wont connect to the router at all when its plugged in because it just keeps resetting itself. I can flush my dns but i cant renew it for some reason. but the internet functions fine.

As for the router, it wont connect. Its just in a loop resetting itself endlessly. Cant get the cpanel for it and the reset button wont work

[freakinprince]

router ok its a dead thing ...either get it replaced if you can or purchase a new one....router deal is done!!!

now what do you mean by internet functions?
if you can't renew it then it might be the protocols...

you have checked the local area properties right?

right click on my network places --> select properties --> right click on local area connection --> select properties --> look around

you can double click on TCP/IP and click on advance button
the first tab should say under Ip addresses DHCP enabled
second tab both inbox are blank but append primary and connection specific dns suffixes radio button is one plus the box underneath it is checked off...
third tab nothing to worry about reallly
and options tab...it should say TCP/IP filtering

if that what it all says then ...damn...it might be something really simple!!!! and we are just overlooking

[Demonstroke]

took a look at what you said above, it all seems to be in order... as for internet functions, i mean internet is working. i can flush the dns but i cannot renew it for some reason. It might be an error on my part when repairing Winsock entries.
