最近我宿捨的無綫網路經常上不瞭網，在連綫時都連不上。

如果選擇WINDOWS的修復，WINDOWS在經過RENEW IP ADDRESS...等程序之後，就會停在CLEARING DNS CACHE這邊。說是"無法清除DNS快取"。

我使用ipconfig /flushdns指令也顯示無法清除DNS快取。所以就一直很難上網.....

請問各位大大該如何解決這個問題呢？謝謝。

PS.ISP是CHARTER(我住在美國)，ROUTER是LINKSYS的。

how about when connecting direcly on the linksys router?
Type IPCONFIG /ALL and check all the setting and make sure the DNS server is correct. Can you ping your Linksys router while connected wirelessly?

Thank you for reply.

Yes I can. I can ping Linksys router when the Internet was down. But I don't know what the DNS address is.

if you are connected to Linksys router, then your DNS setting should be the same as default gateway which is 192.168.1.1 (default unless you change it). Log into your Linsys router and click on WAN Status....make sure it is connected and DNS IP properly display.

Thank you for reply.

So, what is the problem exactly? Do I need to check DNS IP to clean DNS cache?

Can be a lot of things.  Use nslookup to check...for example...my pc to lookup www.yahoo.com i get the following.

> www.yahoo.com
Server:  UnKnown
Address:  192.168.1.1

Non-authoritative answer:
Name: www-real.wa1.b.yahoo.com
Address:  209.131.36.158
Aliases:  www.yahoo.com, www.wa1.b.yahoo.com

If you has no access to the router...it is going to be hard to troubleshoot. Can be WEP key is wrong, QoS or Router is not connected to internet at all....etc. Is there other pc/laptop that is working with the current router? check their settings.
