No Internet Access with Three Mifi

Three ConnectedBernie Goldbach in Cashel having problems with the Three Mifi at left.

I THINK MY WINDOWS laptop has a dodgy internet adapter inside because I'm having headaches with my Three Ireland Mifi internet connection lately.

I'm blogging this problem because I know several wifi experts read my musings. Here is my plan.

1. I have restarted the E586 router several times, waited for it to boot up and connect to my laptop. Unlike my O2 E586, it shows "connected" most of the time.

2. I have deleted the applicable network profile on my W7 laptop.

3. I have uninstalled the wireless adapter driver and discovered some remnants of a T-Link adapter tha might be causing issues.

4. I have reinstalled my wireless adapter.

5. I have rebooted after the reinstallations.

6. In Network and sharing center > Manage adapter settings, I right-clicked on my adapter icon and applied these settings:

IP Address: 192.168.1.200

Subnet Mask:  255.255.255.0

Default Gateway: 192.168.1.1

DNS Primary: 172.31.140.69

DNS Secondary: 172.30.140.69

7. I shut down all protection components (i.e., antivirus and firewall).

8. I manually created a network profile in Network and Sharing Center > Setup new connection nad once used Network > Manually connect to wireless network.

9. I've watched the E586 connect but then lose internet access.

10. I've returned to my laptop after several cups of coffee and discovered the Three Ireland connection was purring away.

Three Ireland gives me more over the air 3G service for less money than any other provider. However, in the shadow of the Rock of Cashel, I cannot depend upon it to give me full duplex video in Google Hangouts. Hence, I use O2's Mifi for that.

I'd like to figure out a way to get reliable Three Ireland HSPA connectivity in my location and with my Windows laptop. I think I may need to put the Three Ireland SIM into a T-Link wireless router and work things out from there.

On a related note, the DNS servers provided by Three Ireland are definitely a weak link. That's why I try to manually insert name server details.


Bernie Goldbach teaches creative multimedia and recommends both Three and O2 over the air service to students in bedsits across South Tipperary--but only after checking local reception conditions.
