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....

The GigE upgrade

On Monday before the rain, I had placed an order on Amazon.com. The large part of the order were the pieces to complete the upgrade to GigE.

The GigE project started when I replaced a 5-port switch that had a bad port. Which was causing me issues because it was either between wireless access point or wired connection for work laptop. Sure I could connect by wireless with the work laptop, but for transferring big files...wired is faster.

That upgrade made no improvement in speed (at least none that I'm aware of...I never did have cause to connect work laptop since that upgrade...so I don't know if the work laptop does GigE...but its a MacBook Pro, so it should, right?)

So, to complete things, I got a 2 more 5 port switches and an 8 port switch. Two of the switch hops are Linksys WRT54GS routers, and the far end is an 8-port 10/100 switch.

As I was plotting how to make the upgrade, it occurred to me that the 5 port switches aren't replacing the routers...so I'm going to need some patch cables. And, the other day I was thinking I needed to stock up on some, because I couldn't find any. Though I'm sure I had some pre-move that I probably haven't unpacked yet. As I was going around looking for cables...I came across some 7ft and 14ft cables, that I must've picked up the last time I was ordering parts (BuyExtras.com)....might be time to stock up again.

So I started the upgrade....first the living room router. I put the 5-port in place. Moved the cable that links router to the 16-port 10/100 switch up. Then ran cable from GigE switch to router. Moved other cable in router to GigE switch (the overhead Cat5 to where my main desktop is...and the first GigE switch.) Success, one port showing GigE link. The other two ports on the router go to TiVo's....they can stay....

I then moved on to moving stuff around at the other router. I first moved the one room cable that wasn't active to the GigE switch and connected GigE switch to that port. And, moved the other two room cables over. I also moved the wireless access point in this room onto the GigE switch (could've gone on the router...doesn't really matter). It was mainly so that it would be on the same UPS as my networking equipment...so some chance things would work in an extended outage. It would mainly be things that were already working before the outage, since DHCP server isn't on a long running UPS (yet). I checked for green light (to show GigE)....there weren't any....sad.... :`( Seems to mean that building wiring can't support the speed?

Oh wait...I think I was short one cable move at the living room router. Sure that its...the room jack is connected to 16-port switch. Get a longer cable (14')...and connect it up. Presto now two green lights (at switch in living room).

Last but not least....upgrade the 8-port switch. First moved wall jack to it and connection from 'lhaven'. Trying not to lose my IRC sessions. And, then move the rest. 2 Green lights. 'orac' is now 1000BaseT full duplex.

Before I was able to get about ~99Mbps with iperf between 'orac' and 'tardis'. Now with iperf...I'm finding I can get ~190Mbps going 'tardis'->'orac'. And, ~300Mbps going 'orac'->'tardis'. Part is likely that Windows isn't tuned for the speed. I did do the tweaking to maximum broadband speed.... Linux is probably just better by default. There might also be the hardware differences. 'tardis' is a P4-3.2GHz w/HT box and 'orac' is a Core 2 Quad 2.4GHz. 'tardis' is Windows XP and a pretty busy machine....while 'orac' spends most of its time just running boinc WUs on all 4 cores. Etc.

Now what am I going to do?

TRENDnet TEG-S50TXE 10/100/1000Mbps 5-Port Copper Gigabit Switch - Recertified

Link: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4603166&CatId=2796

I bought my first gigabit switch. It replaces the 5-port Trendnet 10/100 switch at the end of my Livingroom run.

At that end is one of the computers that I own that has a gigabit network card. The circa 1993 Dell Desktop that is currently my main home computer.

iperf from one end to the other end of my network shows no difference in speed. Of course, I wasn't really expecting to see any improvement. Though it was good to see what I was getting full speed and that it didn't degrade my speed.

The only other computer I currently have that has gigabit is/was the computer at the far end that I was iperf'ng with.

There's a plan to gradually add other gigabit switches to my home network (3 more), before I can finally see what gigabit between two computers is like.

The reason I got this switch, was that I was ordering some stuff from TigerDirect and needed some padding to get cheaper shipping. And, the old 5-port switch had one bad port on it, which was causing me some inconvenience. A switch with more ports might have been handy here since now I have no open ports at this position.

Hmmm, does the work MacBookPro do gigabit? Didn't bring that home, might be something to check out someday....

Not sure what's next on the upgrade plan. Need at least a 4 port in the closet and an 8-port for the other end of my home network (well, at a 7-port). The plan is for a Airport Extreme to go on the HomeTheater stack. Though while there's no Gigabit stuff there now, the going with an Extreme there does limit things...since whatever I put at this location, I would need at least 3 wired ports (one to the 'network' closet, one to my living room computer setup, and one to the Linksys Router or the 16-port TrendNet switch that links Cable Modem into my home network and feeds all the HomeTheater stuff.) Though there is one network run that has nothing attached now, but eventually will. So another small switch might go here interim....

:hmm:

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.
