Connecting to router but rarely Internet, and when I do DNS lookup fails

sure - - the O.P. was posting just to keep you and I busy

When I was with IBM, we were taught to disturb as little as possible less we
fix one issue and just created another.

Another engineering axiom is "The solution needs to be both Necessary and Sufficient";

• Necessary:- in that without a feature the solution doesn't work.
• Sufficient:- the solution solves the problem and does not add extra work

Did you notice I have not suggested any noticeable changes YET? Please READ carefully and understand ALL posts.

hmm; Think I'll sit on the sidelines and watch the master at work :grin:

No no I insist you do your thing. I need to finish some quest (Skyrim) with my level 81 Breton, before I get hit by an arrow on my knee....

I was wondering how long it would be.

Just something to check on, sirsnipps... What internet security settings or software are you running? I ask, because I was experiencing very similar behavior on my son's computer, and it turned out to be a flaky setup of Comodo firewall software. For some reason, the Windows firewall was on as well, and the system kept flipping the "network detection" settings between established private network and a new unknown public one. It was driving us bonkers for the longest time, and we ran round and round with different wireless connectors, etc. But, as is happening with you, even wired ethernet had issues, which pointed me away from hardware and towards something in the drivers or operating system. Once we uninstalled and reinstalled the security software, everything worked fine.

Might be worth a check...

The dongle -> direct to the system works fine, which says

1. dongle is ok
2. system is ok
3. firewall is ok too

imo, the router

• settings need to be adjusted
• may not be compatible with this dongle
• just may be dead

Hmmm, maybe I'm reading it wrong, but I was understanding that he couldn't connect wirelessly, through direct ethernet, or with an external dongle. Which sort of points fingers back towards system and/or firewall, considering everyone else is having no issues with the same router (so it can't be dead)...

OOPS! Please excuse me; I seem to have crossed my hands with this thread and the Sapido router+dongle issue

In case you haven't read carefully all posts, probably you have not. The router could not be dead, it is functioning perfectly as dhcp server.

Hi guys, sorry for not replying for ages, I didn't exactly have access to the internet. As it turns out it's all fixed and the problem was so obvious I'm almost embarrassed to tell you. As Vrmithrax suggested it was simply that my firewall was out of date since it couldn't update, uninstalling it fixed everything. The stupid this is I did actually think of this when it first happened but for some reason never did it.

Oh well! Thanks for all the help everything, I appreciate it.

I thought you have already tried disabling the firewall but still no luck. Anyway it is good that the problem has been fixed.
