Hi Folks,

I have a Huawei E3373 4G dongle that stubbonly refuses to even find the O2 network let alone connect. I'm confident the SIM is correctly inserted as it picks up the SIM's number ok (and is quick enough to give an error if the SIM isn't correctly installed). The SIM has been activated and there is credit on the SIM (although this obviously isn't registered). And as far as I can tell it has the correct network and APN settings (although I'm happy to check this if anyone can point me in the right direction)..

According to O2s coverage map I'm in an area of good 3G and 4G coverage and my phone doesn't appear to have any issues so it's left me a bit bemused and frustrated about what's wrong.

If it's useful the hardware version is CL2E3372HM, the software

22.200.13.00.405 and the web UI 17.100.11.03.405 although I've not found any updates for these.

One thing that does puzzle me though is that all the pictures I've seen of the web UI show a log-in button on the top right of the screen and all of the instructions say to click this as one of the first actions however this is missing from my UI.......

Any thoughts?

Does the SIM work in a normal phone?

Are you sure that the dongle is not network locked in any way?

Have you tried any other SIMs in the dongle?

Its not obvious its a button if its like the 3G one I use. it also seems to not like it unless its battery is fully charged, but maybe that is just me. I assume its got the usual lights about charging etc. Brian

To test out the functionality for the E3373 4G device get one of the free Three SIMs and give that a quick try. Mine is badged "Three" but was unlocked before I got it - maybe yours is still network locked?

Or have you got a SIM that will only work in a mobile phone?

What browser are you using? Whenever I have used one it has either shown me the data balance on the SIM or taken me to the buy some more page.

Just noticed you said dongle. If the dongle is plugged directly into a particularly badly made portable or a well made desktop it may be respectively blinded by RF noise hash leaking from the portable or screened from the mobile signal by the big metal case of the PC.

Try it on a 1m extension cable to move it clear of the PC influence. My dongle works better (faster) when it is at least 0.5m away. YMMV

Indeed, I have one on a cable which is probably 4m in length. The dongle is cable tied to an old style picture hook, over the picture rail. The other end disppears into the back of the server/network rack and plugs into the VDSL router; it would have no hope of a signal in there.

It works fine (auto failover for the VDSL).
