Specification : 64 bit Windows, Core 2 Duo
Network components used :
- Wifi - Intel 5100 AGN
- Datacard - NDIS based - Huawei 3g
Issue when using Wifi :
- Every 15 minutes, internet connection gets lost for about 10 seconds(It is confirmed this is due to the ISP. The data lines have issues and periodic issues keep happening.). Then everything is clear from ISP end. But chrome and firefox cannot resolve the tlds.
Restart is done. No changes are made to the modem and router. But now, chrome and firefox resumes resolving the tld.
In the above scneario, if I plug in my data card, everything works. Chrome and firefox detects this is a new network, a new ip and things work fine.
What has changed now? Is there any windows command I can execute that will do all the things which a restart does for network.
My diagnosis : Once chrome and firefox understands network is down, it assumes things wont work on the same network. The cache of DNS used by these browsers causes some kind of issues.
