Connectivity

Internet Connectivity Update

In this post, I discussed my emergency backup system for when my house or apartment Internet connectivity goes down. In that report, I mentioned that my WiFi connection in the apartment was getting reasonably flaky.

We’re in the apartment all week this week, so I was bracing for the experience. As I mentioned before, the WiFi router wasn’t far from our laptops, roughly 21 feet. There is a bathroom in between the two rooms, so there are two walls for the signal to travel through. Still, most of the time, it works well.

When the link is up, tests show an average download speed of roughly 3.6Mbps. Upload speeds of roughly 364Kbps.

On Monday and Tuesday, we had a few drop outs, but they were relatively short lived. Yesterday morning, we lost connectivity, and it didn’t come back within five minutes. I could have put the emergency plan into action, but I decided to try something else.

I have tons of extra (mostly ancient) networking equipment. In both the house and apartment, I have a pair of old Netgear XE602 Powerline Adapters. The pair in the house never get used, because the one place I could have used them yielded a near-zero signal. In the apartment, I have used them on rare occasion, but they worked reasonably well.

So, yesterday morning, I grabbed the pair, plugged one end in next to the main router (in the remote room) and brought the WiFi router into the bedroom, and connected it to the other XE 602. We immediately had a connection. It’s possible that the reboot of the WiFi router (even remotely) would have corrected the problem.

More important, when I did the speed test, I got 5.2Mbps down and 494Kbps up. After a while, even though I didn’t have a problem, I switched to a wired connected (since the WiFi router was close enough to my machine to just plug in directly). Lois remained wireless the rest of the day.

We never lost connectivity, but at least two times, there were instantaneous blips that would be unnoticed by humans (normally), but occasionally cause my SSH client to drop the connection to the server. I think it’s the Powerline devices (they are no longer sold new, and perhaps newer generations ones wouldn’t exhibit these problems). No worries though, this is way better than what we were experiencing.

For now, I’ll leave it set up this way. We have company coming in tonight, and staying the weekend. I don’t know if they will bring their laptops, but if they do, I may need to relocate the WiFi back outside, to give them a workable connection. We’ll see…

Internet Connectivity Insurance

In the house, we have Verizon FiOS service (triple play, Phone, Internet, TV). In the apartment, we have Time Warner Cable (Internet and TV). Both services are very reliable (in terms of availability). Beyond that, Verizon FiOS is so dramatically better, I keep praying for when they’ll figure out how to deploy it to large apartment buildings in NYC.

The biggest difference in the service is the speed. On the FiOS link, I have 30Mbps downstream, and theoretically, 5Mpbs upstream (though no site seems to accept data at that rate, so it’s somewhat meaningless). On the TWC link, it’s between 4-5Mbps downstream, but a poky 364Kbps (yes, K, not M) upstream. Most of the time, that’s OK, but when sending large attachments, or updating a large blog posting ;-) it can be reasonably painful.

The other difference (for me, not between the services) is that at the house (on FiOS), I’m wired the entire way. At the apartment, I use WiFi. Lois uses WiFi at both places, and it’s rock solid at the house.

At the apartment, the WiFi is often flaky, even though we’re not all that far from the access point (it’s in another room, and there’s one wall between us, but it’s not more than 20 feet away). At some times, it’s rock solid, at others, it can drop out completely.

It’s possible that the router itself (a Linksys WRT54G) is flaking out. On the other hand, sometimes, it can go for days on end without a problem. Slightly more likely is the fact that we live in a heavily populated area, and there is likely a crazy amount of interference of all types on the 2.4ghz band.

So, this past Wednesday we drove in from the house to the apartment because we had tickets to see Keith Urban and Carrie Underwood at MSG that night. (Completely unrelated to that post, here is my review of that concert…)

We got to the apartment mid-morning and immediately logged on. The weather was horrible outside, and it’s possible (though I can’t imagine how) that it affected the WiFi signal as well. Within minutes of being logged on, we were experiencing tons of dropouts on the WiFi. The TV signal was fine, and I was able to make VoIP calls (which bypass the WiFi) without a problem, so the basic Internet service was definitely up as well.

After about an hour of complete frustration on our part, I decided to put the backup plan into action. As the name of the post implies, I have insurance for just such situations. For a few years now, I pay for an unlimited data plan with Sprint to use each of our Treos (I have a 755p, and Lois has a 700p). It’s not cheap, and I would probably save a ton of money if I paid only when I used it (because it is, after all, just for emergencies), but I really hate metering, and getting smacked with out-sized bills, even if overall, it would be cheaper.

Years ago, when few hotels had free WiFi, it was a very good deal, as we often both used our phones as modems for hours on end. Now, it’s actually rare that we stay at a place that doesn’t have free WiFi. Therefore, it’s also rare that we use the Treos to connect our laptops to the Internet.

On Wednesday, I pulled out both phones, connected them with USB cables, and connected via Sprint. We both stayed connected for at least six hours, never had a single drop of the connection, and neither of us felt that it was sluggish in the least. I didn’t measure the speed that day, but in the past, in the apartment, it has averaged roughly 400Kbps downstream and 100Kbps upstream.

I would hate to see what that one day bill would have been, which is I pay the set amount each month. Ironically, this is the second time this month that we’ve used the service. When we were visiting my folks on February 6th, Lois needed to do a ton of work (thankfully, I didn’t). She was using the WiFi in their apartment, and it was working fine for everything, except sending mail. Obviously, it was critical that she be able to send emails.

I realized fairly quickly that Bellsouth (excuse me, AT&T) was likely blocking outgoing SMTP that wasn’t going through their servers, but I wanted to visit with my folks, and I didn’t want to dork around with her machine, or my server. So, I just plugged her in to the Treo, and connected to Sprint, and she was fine for hours.

The next day, I just changed her settings to send through Bellsouth and that worked fine too.

So, while I’m definitely overpaying, I’m very happy to report that at least on the rare occasions when I need it, it not only works, but it works flawlessly, and provides a very satisfactory experience in terms of speed as well. That’s exactly how all insurance should work. :-)
