Theoretically (I only have one), however each layer would have to be "authenticated" if security is on. Also note there would be more interference since the original and repeated wifi will be on the same channel. And the antennae would have to work well to transfer the signal along the chain.

Ahhh, I see.

I have long considered getting some of the current Meraki plugs, which you could use for this purpose - just scatter a little trail of them between you and the source and let the meraki do its magic.

It has the plug form factor that I am looking for - the only downside is that the meraki plugs don't take an external antenna. Now that I think about it, I'll bet that's a business decision ... why sell two meraki plugs with big antennas when you can sell 8 of them with no antenna ?

Ok, I bought one of these from 3gstore.

I'm not really interested in the whole "use one SSID forever" aspect of it, so let's skip that. What I am really interested in is the repeater aspect, and the ability to "reach out" and use a faint wifi signal when necessary. I've found myself in that situation a number of times - like in a hotel room at the far end of the property, and so on.

So with this in mind, I'm having some trouble seeing how this works... I'll cut to the chase and say that this device needs power and sensitivity at least 2x that of a typical laptop/usb/whatever 802.11 device to make any sense at all, and it appears that it does not.

Some details...

Let's say you're just far enough away from a wifi signal that it doesn't work. Now let's say you halve that distance. Certainly you'll be better off, but all else being equal, you still don't have a great connection - maybe you'll get it to work, but you'll have some slowness and timeouts and interference and so on. In fact, my experience is that it'll work just well enough to be annoying.

So now, enter the pepwave, and that's about what you do get. Presumably you set it halfway between you and (the wifi) and you'll have the issues I just described, but on two links instead of one, all else being equal.

That is why it is imperative that a device like this be _at least_ 2x as powerful and sensitive as your end user device.

So, is it ? I don't know. I have no testing equipment ... spec sheet says 200mw, which isn't huge (my Alfa USB is 500 or 1000, depending...).

Perhaps I am using this wrong ? I am even using it with a larger 9db antenna, and it's really underwhelming.

Bottom line for me: a repeater like this makes sense if it is _much, much_ stronger than your end user device. If it's the same, or a bit more powerful, it's just going to be a pain.

Going a bit further here ... if you're curious, it's because I _really_ want a dead simple wifi repeater to drop on the side of the road from time to time when needed....

The other main problem with this device, which is shared with the "nicer" surf 400, is that there is only one antenna lead, which means that you cannot fine tune reception with a directional antenna ... because then your client system won't see it. You can only point one way, and two ways are needed.

Does anyone else have any comments ? I would love to see a reasonable way to use this item, since, again, I really want this to work ... but I think you need to have two antenna ports, otherwise you can't lock in with a directional antenna ... and as I said before, you really need an over the top power and sensitivity, and 200 mw just isn't interesting...

Please comment/critique/insult ....

PostPosted: Mon Oct 04, 2010 10:03 am    Post subject: One horrible thing - bounce pages

The only thing really bad about the pepwave, is that when it disconnects (and you need to be looking right at it to see if the remote has gone down), it uses DESTRUCTIVE bounce pages. e.g. your cnn.com/reallly/long/deep/complex.url gets zapped, erased, destroyed and replaced with the connect page.

This happens in firefox. The NoRedirect extension can sometimes help.

And there is no way to disable this. Cradlepoint fixed this long ago.

The problem is not so much the notification, but they are violating HTTP by telling my browser that cnn.com has been destroyed, no longer exists, has passed on, and instead the actual page has been replaced by this pepwave page (instead of saying it was temporary or an error - a 404 - click here would at least preserve the history).

Since I've been both traveling and at home, I've not wanted to get high-speed internet installed and only use it 1 week each month. That has changed, but over the summer, I've been using the PepWave. My condo overlooks a number of open access points (local eateries mostly, and I do go there to eat).

The first thing that helped was a 9dbi or greater omni antenna, but I had to have it pointed just right (to avoid interference - it picks up everything).

What ended up working perfectly was an 18dbi Yagi from DealExtreme (they have a 16dbi for a few dollars less that would probably have worked as well, and they have quantity discounts).

http://www.dealextreme.com/details.dx/sku.33016
http://www.dealextreme.com/details.dx/sku.34759

(They had RP-SMA connectors for the PepWave and some USB adapters so I got one when ordering some other gadgets - there are other suppliers with similar things)

Note these are NOT the cell phone band Yagis, these are 2.4Ghz which is where the wireless band is.

It only receives in a 30 degree or so cone so I get just the AP I want with higher signal strength. It is only slightly awkward/bulky, but the rod antennas had to go at strange angles too, and the next thing up is a fairly large dish (yes, I have one of those too).

If you are at some distance from the AP, or are at a place that has many APs all on the same channel so interfere with each other, a Yagi would be a real problem solver.
