before I start this is the equipment I have:
laptop-vista
pc1 - w7 32bit
pc2 - w7 64bit.

router Linksys WAG200G - Firmware Version: 1.01.09

Whenever I reboot the router my systems loose internet. its mainly the pc's as i dont use tha laptop that often now.
when you go to network and sharing center u can se an exclamation mark and under router it says multiple networks.
in ip config i have 2 gateways 0.0.0.0 and second one is 192.168.1.1
i can ping the geatway and connect to router but still no DNS coming downt from DHCP. I have found a sollution to this is preaty simple just disable network adapter and enable. i have messed with this for ages and cant figure out. I have placed this here as I am preety good with networking and i think this is vista/ windws 7 problem. this problem never occured when I had XP.
this has been tested as well on a second router (some cheap aksa).
Mayby one of you guys investigated this and found a sollution There must be some service or something that casues this crap.

edit: I have tried this on manual IP address with manual DNS, no difference
 
most providers reboots the adsl link 1once a day. happens then
Genarally evry time I come back from work it happens. i dont reboot router my self.
besides even if i am rebooting my self I would expect you to write a possible solution not a wortless comment.
only thing I found about this yesterday was this:
http://www.annoyances.org/exec/show/article04-500

works on my w7 64 bit so far. but not on my gf computer the w7 32 bit

Er, no they don't. Even if the "adsl link" is being "rebooted" (which I presume means you're losing sync), it shouldn't be making your router restart.

Does ipconfig /renew fix it? It's certainly not something that happens here with Windows 7, x64 or otherwise :confused:
 
network card drivers upto date? even when windows detects your hardware natively, it's always best to get the latest drivers direct from the manufacturer.
 
ok Got to admit i might have over assumed with the ADSL link reboot. but please focus on the problem.
multiple networks are displayed in my network and sharing center.
I understand that I can fix this in 10 seconds be disabling the network card and enabling it again or doing ipconfig /renew. I do not want to know how to fix this problem once it happens as I know perfectly well how to do it.
I need to know how to prevent vista /windows 7 from detecting mutiple networks evry time I come back from work.

re: marc2003 network drivers problem is impossible casue I tested with following integrated NIC's: nvidia nforce /marvel/ intell and atheros wireless card.
unless u assume all this companies drivers have this problem

Could this be caused by my router being old. I noticed some newer routers back when Vista was rolling out used to have Vista ready on them.
I dont know I run out of Ideas. and if you check the article I attached It points to the fact I am not the only person with this
 
We're getting two things confused here. Is your router restarting, or losing DSL sync? I can't make it out from your posts. (Your ISP won't resync your connection, but there are other reasons why it can happen.)
 
ok sorry this is confusing.
router is ok no problems status is fine and working. vista and windows 7 systems keeps detecting some strange network and displays multiple networks in network and sharing center. once it is stuck like this it will not work untill you disable and enable NIC. in same time my other computer can be working perfecty fine. this is stricktly and only on windows vista and windows 7 as on windows xp i never had any issue like this
BTW while your internet is not working you can still ping the router and see the router config page and its all ok there.

I found this thred today about this. http://www.eggheadcafe.com/conversation.aspx?messageid=31636469&threadid=31636464
and some ppl sugest to disable ip version 6 and use some cmd comands to remove some invalid routing table entries from CMD with this comand
route delete 0.0.0.0 0.0.0.0
I will try this next time it happens and let you know if this helped
I have alrady disabled ip v6 today so will se if any results in coming days.
I read as well that and this is not related to router or adsl link reboot but mainly after PC goes to sleep and comes back with this problem or after u swithc PC on. I will do some tests in a sec
 
What it sounds like is happening is:
1) the router restarts (either by user intervention or otherwise)
2) Vista/Windows 7 gets a mangled DHCP response (perhaps when the router's starting up)
3) the machine then gets a proper response but holds onto both

As you've discovered, and non-answered to what I asked, you don't have to disable the network connection but renewing the DHCP lease is enough to fix it.
 
Its not DNS
please see below I followed some of the instructions I found on other sites maybe that will put some light on this problem,
and be aware that this does not resolve this issue as this still comes back after reboot (i have ommited certain entries and wil use different collors to make reading easy:

as you see above the invalid routing table entry in windows 7 creates this problem
after deleting this entry and readding correct route to gateway it works ok.
after i rebooted my gf comuter problem came back
i will write a script so she can double click and it will run the comands to delete the entry but this is not the kind of sollution I want
 
re Mattus - ipconfig /renew does not work. tried it after u asked me.

re Tolien- from my above entry I hope u see that this is nothing to do with router.
its strictly a windws error
 
ok this seems to be casued by windows firewall. I disabled on both computers and seems to be ok.
will try to investigate further why windows firewall adds this routing table entry
 
now with firewall switched off this does not happen after reboot. but when computer comes back from sleep this still occures.
