Travel Router - ZuniDigital ZTRP150

Link: http://www.zunidigital.com/?page_id=222

Some time before I bought one, I had often wished I had a Travel Router during my travels. And, I know I looked at whether it would be possible to use my Linux laptop as such.

But, then on November 25th, 2011, Black Friday....meaning I was at Chicago TARDIS at the time....I had on the spur of the moment ordered the ZuniConnect ZTRP150 WiFi Travel Router with USB Charging by ZuniDigital from NewEgg.com.

As I recall, it then sat around for months until I finally set it up, in preparation for possible use on my next trip....Gallifrey One in 2012.

The turn hotel ethernet into WiFi for all my gadgets was really nice, since most hotels only allow one device per room to register for its free or pay wireless. (though I heard some allow pay per device....) But, my reasoning at the time was the large number of Eye-Fi cards that I have in my collection, which are unable to connect to such WiFi, even when its free and its just an EULA page that needs to be accepted.

Otherwise, I wasn't too WiFi dependent gadget heavy then....I could use 3G on my smartphone, and my Kindles all did 3G or something (either exclusively or later with WiFi...I had started carrying the Kindle Fire, original, on trips....so it was the first that would benefit from a travel router.)

It was November 23, 2012 that I started my journey into the world of Chromebook (I had preordered it, and that's when it shipped....at first I was traveling with both my Linux laptop and the Chromebook, but for some time now...I've been going with just the Chromebook. Which has been challenging, like now I can't add SSIDs to my eye-fi cards on the road. So, I have to hope that I got the right ones pre-added to the cards. Along with some of the ones I know what will work, like the SSID for my MiFi2200 or later tethering off of my HTC One (I got the 5GB tethering plan, because lower tiers weren't eligible for employee discount and I had been looking to upgrade from MiFi....but hadn't found a reasonable pay as I go, but can't be activated because I don't live in an area that's covered by it.

Though I did consider exiting the Smartphone crowd and getting a contract Mobile Hotspot, but there isn't anything in an Android 4.3/4.4+ equivalent to iPod Touch....or WiFi only smart phone ???

Now, I guess I've been lucky with the ZuniConnect, which has two modes, Router or WISP. It has both a WAN and LAN port, so there's lots of different ways it could be used.

Long before this, I already had a RoadWarrior travel Ethernet cable in my carry on....so I wasn't stuck if the room only had a jack. And, the router mode was all I needed. It was pretty much plug it in and go everywhere that I stayed.

That was until my previous trip....the one to visit my brother and parents for Christmas. The hotel I stayed at didn't have Ethernet in the room. I had never looked at WISP, but knew it was something I was going to need to use eventually.

Well, it was a bust, because WISP is largely a different configuration in the router, because I would see ZuniConnect or something as an SSID sometimes, but not be able to connect to it. Not sure I know how to connect Chromebook to WPS, or if its possible. etc. But, in the end found that the only way to configure WISP is through ethernet. And, none of my devices had ethernet ports. (I'd still be screwed if I had a MacBook Air along....)

So, I made a note to investigate alternative Travel Routers and to acquire a USB Ethernet adapter for my Chromebook, etc. I eventually got both as part of a larger order from Amazon.com on Jan 22, 2014. I got a "Plugable" USB Ethernet adapter, because it was specifically listed as an adapter from Chromebook. And, I got a TP-Link TL-WR702N, Which sounded like it also did all I wanted, had been favorably reviewed and I've been pretty happy with the TP-Link TL-WR1043ND router that handles my Cox connection to the world....doesn't do all the stuff I liked doing with DD-WRT (though I could DD-WRT it)...but its been rock solid, and since I've moved to running nginx reverse proxy on a DMZ host, the 16 port forwarding limitation isn't an issue. QoS might start to become a concern though. But, I still primarily do that through DD-WRT on AT&T connection to the world. Some day I think I want to try pfSense....

But, that hotel stay wasn't a problem since they're WiFi access was controlled by a password that is given out at check-in....so I could connect all my devices to the WiFi without problems.

Anyways....these items sat around in their packages, until the night before I was to depart for Gallifrey One 2014.

The USB Ethernet adapter just worked and wasn't a problem (though I haven't registered its MAC with my network, which only does reserved DHCP ... its on my list to create a guest network, which can be helpful for discovering MAC address of devices that don't have them printed anywhere on them. But, it hasn't been an issue with wireless devices, since those failed attempts show up in my radius log. Which probably also shows up in the dhcp log (I suppose I should set those logs to forward to zen, so I can see them and add them to the appropriate files in CFEngine 3 repository....still haven't gotten cf-runagent working though.)

The TP-Link TL-WR702N was another story. Again it looks like it needs to be configured manual for WIFi Bridging through its ethernet port, but the ethernet port being dual mode LAN or WAN, its out of scope for its built-in DHCP (which is also disabled by default...) Also of annoyance was that its SSID was fixed, couldn't tailor it to my convention, but rather its own convention ending with the last 3 octets of its MAC. Where the default password is the last 4 octets. It does allow you to change the password, along with other encryption settings, or go open. It has a dropdown list for channel, which had defaulted to AUTO. But, it won't allow you leave the page until its been changed to be the same channel as the selected WiFi. Seems its a flaw with all WISP, that they attach to BSSID.... I have two APs at home, both with the same SSID, but different BSSID (of course) and different channels. Yet, my bedroom is still in a hole.... :))

Could be interesting in a hotel environment where there's going to to be many different BSSID/Channels, which might change throughout the stay.

But, I ran into a problem. I couldn't not get my Chromebook to connect to the Ethernet port. It didn't do DHCP, but Chromebook has options to set things manually, but Chromebook still wouldn't connect. I suspect there's something Chromebook expects to get answers for to determine that the connection makes sense, and the TP-Link doesn't do it. At first I thought the Chromebook was expecting a fully usable Internet connection....which doesn't make sense, since its able to use captive portals, though often the captive portals only block http/https initially, or provide/leak enough to satisfy my Chromebook.... That was until this Gallifrey One trip....

Morning Orac outage

Well, Orac was being somewhat unresponsive this morning.... Looks like early this morning the system stopped answering to Cacti, with the temperature of the GPU rising to a new high. Don't know what the high would've been, because there was no snmp data for a while. GPU temp did recover, but the display did not.

Ended up rebooting, needed the excuse to see external journal work....

Once backup, I switched back to internal journal...but one of maximum size rather than default size. And, then shutdown the system to extract the PCI Compact Flash card. During the reboot to see external journal work...I realized that I wasn't likely to see much performance gain from getting faster compact flash since the card itself was only UDMA/66. So the 133x CF is already faster than the card?

Probably should've fsck'd manually after the switch back....some discussion thread suggested doing this after fiddling with journal settings. But, its fsck'ng now after the boot back up. Apparently superblock had invalid external journal superblock hint? And, auto fsck failed, requiring manual fsck.

Downside of internal journal is that it can only be a max of 400MB (an improvement from the 128MB default I had before)...but that's only like 0.01% of my total space. And, there was a discussion thread that seemed to suggest a journal size of 0.2% would yield better improvement....I didn't do the whole 16GB CF card...though wonder how much that would've helped.... But 0.2% would call for a journal of ~10.9GB. Suppose I could turn off data journaling, especially since there are files that backuppc puts down that are bigger than the 400MB journal. Though I think the ordered/writeback modes usually just do metadata journaling, while I had switched it to data journaling when I was playing with external journals...but I didn't switch it back.

Wonder which of writeback or ordered would be more optimal for this FS? :??:

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
