Port 53 is used for DNS and it almost seems as if you are tryng to set up a server that may be accessible from outside your home. If that's the case, please understand that Residential installations cannot be accessed from outside your local LAN because the satellite network is protected behind a double-NAT. Only Business installations may be accessed this way. Disregard if you're merely trying to set something up that's accessed within your local LAN.

Clearly you haven't read everything, because: 1. Not all people have other options for internet access. 2. Not all people use the internet as a means for watching TV.

The 'signal strength' is really an inverse bit error rate on the data stream, which can vary by humidity. Any kind of water in the air at these frequencies will defract (diffuse?) the signal, making it more error prone, although you might not see those errors due to redundancy and forward error correction protocols. A real dry day (~10-20%) could cause a 'strength' of 125, whereas mild humidity (~40-50%) could drop it a bit lower. Both these instances could be bright, shiny days with no rain at all (which of course, would be above 90% humidity).

Correct. HughesNet already uses an http (web) accelerator as well as a TCPIP accelerator for other protocols. They are already maximizing as much of the downlink channel as possible. Adding another accelerator on top of that won't be beneficial and may even inhibit the ones already in use.

A ping is essentially a singular event and measures the round trip access time for that one event. Accessing a web site or streaming server just for one access may be several events, depending upon additional content (images, stylesheets, javascript, etc.) and/or secure authentication processes, which in iteself is a multi-access event due to handshaking. So more complex than a ping, and the latency effects are cumulative.

Unfortunately speed has very little to do with buffering. Buffering is from latency, congestion, and how streaming servers deal with those factors from satellite internet providers (e.g., not very well)

I've noticed this happen when the congestion is extrememly high. I assume what's happening is there is a 'heartbeat' connection to the web acceleration server that just times out. It then assumes it's unreachable and automatically disables it. Sometimes rebooting will get you on a better connection, but as you've seen that is not always the case. When the congestion is that high there's a possibility that you're already on the most reliable channel available.

Not necessarily a HughesNet caching issue (actually I don't think they cache at all), but the latency may be playing a part in the browser recognizing the page had changed. Killing the tab, opening a new one, then loading and optionally shift-refreshing the page should update the browser. Also, if your site is cached if it is behind a Content Delivery Network (CDN) like Cloudflare (more like a large network of caches). You may have to purge everything in the CDN's cache before doing the above. Sometimes I even have to purge when making changes to my .htaccess file, not just pages. I seem to go through this all the time regardless of what network I'm using.

As everyone knows, Texas is experiencing power outages state-wide due to their extreme weather (I'll try to keep my other opinions to myself for the other reasons). This presents a few problems: 1. If your gateway is in El Paso (ELP), your modem might be operational, but you'll have no connectivity to the internet because there's essentially nothing for your modem to connect to in order to get to the internet. Nothing really can be done until power is restored to El Paso, and that may be limited if the site is subjected to rolling blackouts. 2. The internet provider of other gateways will have to dynamically re-route around places in Texas where there's no power. Again, if those sites are experiencing rolling power outages it may be hit and miss, and hopefully VERY dynamic. 3. If the site you're trying reach is IN Texas, well... it goes without saying that will be hit and miss as well. Keep in mind this severe weather is now moving Eastward, so both 2 and 3 above may not be limited to just Texas for the next few days.

When it's fixed, you should be able to block by the domain name, e.g. *@zedline.com. That should stop it for a week until the domain changes. Admins may want to relay this to the engineers: Majority of spam will come from web servers that have been compromized by hacked web site plugins as a means to get around checks to the RBL, but it doesn't last long. That said, it's best for the email server to check the HELO IP of incoming messages against an RBL and reject as appropriate. It's one of the best defenses to kill this beast. The current checker they have in place doesn't seem to be doing this.

I'm having a blast with these things. It's really gotten me back into radio. I mainly use the RTL-SDR for experimenting with HD Radio (nrsc5, nrsc5-gui on github) and a trunk tracker called SDRTrunk (also on github). All my DXing is done on the AirSpy HF+ Discovery using Gqrx and a thing called SdrDx. The AirSpy is a lot better with sensitivity and dynamic range/image rejection than the RTL-SDR, especially on HF. The RTL-SDR runs a little hot too, so it may be very possible that it has a bad solder joint somewhere. Edit: Forgot to add that on HF the AirSpy does especially well with digital signals. I can output a DRM signal through a virtual audio cable and decode it using Dream, or do something similar using SDR# in a Windows VM and pipe the audio into MultiPSK. Working more signals than I ever did with my NRD-535D!

The DNS server wouldn't account for the DNS cache inside the modem getting corrupted. In fact, the DNS cache getting corrupted is likely more an indirect result of many DNS queries during a lengthy ping gap. As far as what's causing the gap, it could be anything from a bad Operating System upgrade, to some hardware inadvertently tying up processing. Something I've even seen lately while using an RTL-SDR is that they can wreak havok if the USB connection is disturbed, almost to the point of causing cyclic kernel panics on my Mac. As an aside, my AirSpy HF+ is a much better device for HF and limited VHF (and isn't as finicky), but the RTL-SDR goes DC-daylight and is best for monitoring trunked comms.

Looks as if something jammed up the modem, which re-powering solved. The inability to contact the acceleration server was a symptom of that, but not the likely reason. This is also likely separate from the lag issue. Incidentally, whenever I see something like that - to include not being able to reach a particular web site - that's the first thing I do: re-power and clear the modem's DNS cache. I wish there was a more expedient method to solve it but there isn't. I still find the high lags very curious. You, maratsade and myself are all on the same beam and we don't experience anything quite that high. This points to something local to you. Has your modem ever been replaced? Installation inspected? Or, perhaps something on your computer is interfering with the TCP stack?

A Byte is a character. Multiple bits make up a character. Depending upon the number of control bits, there could be between 8-12 bits per Byte. I use 10 as a general rule, going back to the old signalling days when you had 8 data bits, 1 start bit, 1 stop bit and no parity bits. Therefore, using simple conversion math: 1,000,000 Byte 10 bits 10,000,000 bits 1MBps = -------------------- * ---------------- = --------------------- = 10Mbps sec 1Byte sec

As long as the port forwarding is within your local LAN you can back the router into one of the modem's 4 ethernet ports in the back. Port forwarding for things that need to communicate outside of your LAN won't work because your modem on the HughesNet network is behind a double-NAT. Incidentally, this also provides a natural firewall since no one can access your LAN from outside the HN network.

Guarantee this is not a HN-specific thing, though. I see the same kind of spam on accounts other than on HN, which are evading spam detection. There's been a rash of it for about a month now.

Although what Liz says is true for legit advertisers, please be careful that the email is from who it says it is. If the "From" address looks sketchy or doesn't seem to match the product, I'd advise not hitting Unsubscribe. In those cases the link is used to verify a live email account and somtimes may lead to even more spam.

Could be a bunch of reasons. One that I know of in particular is that a recent batch has been very effective at avoiding spam detection. Another possibility is that when HN moved the email accounts there was a problem where the particular folders were named different from where the new email system was supposed to deliver the spam (folder named 'Spam' vs. 'Junk').
