Not a problem. 3. Some new routers are set to auto-update their firmware, which isn't really recommended. This is mainly because it will use data as this may happen often on new models. However, if the update doesn't work correctly it can end up auto-bricking it. I generally prefer doing those things manually so I can see what happens and not be surprised. If anything goes wrong it won't be happening while I'm sleeping. 4. As long as the router has 802.11ac and you're able to create an 80MHz wide channel on it you should be ok. Again, this is just as long as there is no overlap in channel usage because they may interfere. I think an 80MHz wide channel actually uses four distinct 20MHz wide channels, so it's going to take a little bit of frequency management to avoid collisions with the modem's wifi.

In theory, you might be able to do what you're saying if the wireless router is on a different channel(s) than the modem's wifi. That said, because of the extreme length, you may want to consider using something that might be a little better for long runs than Cat5. 200 feet of Cat5 may introduce consderable signal loss and may be vulnerable to radio interference - both may cause you problems down the road. I mean, you're basically operating within Cat5's maximum specs, but Cat6 or Cat7 might give you better overall performance at that length in the long term.

True. Have mostly seen that happen when there's a storm and the signal quality is very low.

Your solution is correct although the diagnosis is not. Your modem's not near death but your wifi may be getting stressed with repeated weak hits to where the local DNS cache is getting trashed. Rebooting the modem clears the DNS cache and solves the problem.

I'm no where near my old 360, but double check the settings on your X. If the UPnP setting is active, consider disabling it on the XBox as well as in the modem's wifi settings. For some reason (likely the lag) it doesn't play well over satellite.

It could be that the DNS corruption already propagated to whatever you're trying to reach Amazon on. the recommended procedure would then be to: 1. Turn off all devices that are using the internet via the modem in question. 2. Remove power from the modem. 3. Wait 60 seconds, then apply power to the modem again. 4. Wait 5 minutes until the modem is fully activated with all lights on and turn on the devices you turned off in step 1, one by one. This will ensure that every device's cached DNS starts from scratch and can't be re-propagated.

Cached DNS entry to images-na.ssl-images-amazon.com may be corrupted. Try rebooting the modem and see if it fixes it.

@CWM030 wrote: @GabeU @@Liz Its weird because I can unplug the modem, wait 30 sec and then plug it back in and everything is fine again without clearing the cache. But, that's precisely the procedure for clearing the modem's DNS cache. It's possible that instead of poor wifi there's a site or some application that's hitting the DNS too fast, and not waiting for it to respond in time before going on to something else. That will confuse it but is kind of a rare situation. I used to see it a lot with the 1100, but not with the 2000-series modem.

Is it the only device connected? Once the DNS is corrupted by any one device, it affects all of the devices connected to it.

Usually this is a symptom of an erratic wifi connection that has corrupted the DNS, not a problem with HughesNet or the modem. You can solve most of the problem by moving your device closer to the modem or by using a LAN cable.

Technically, an ethernet cable is going to always provide the widest bandwidth, therefore the greatest thruput, which will always seem faster. Wifi depends upon the protocol used: 802.11ac when using multiple 20MHz channels (up 80MHz wide) will approximate ethernet thruput, whereas 802.11a, b, g using a single channel will not. Data is data and neither uses more than the other, however a wider/faster path will always use data *faster* so people tend to think it's using more data.

One other thing I recently noticed on macOS: There's this process that periodically (and very inefficiently) synchs a lot of data at a 1-2 Mbps rate to your iCloud account. Seems to go on for a very long time, and I've seen it happen twice a day.

Looks like an SSL error, which may mean the DNS cache is corrupted, which happens time to time. Try rebooting the modem to clear the DNS cache. If that doesn't work, it may mean the corrupted DNS entry may have propagated to the device you're trying to reach Podtrac with. In order to fix that, you generally need to refresh your device in a manner that doesn't allow the corrupted entry to re-propagate over the LAN: 1. Turn your device(s) off. 2. Remove from the modem at the wall socket. 3. Wait 60 seconds and re-power the modem. 4. Wait another 60 seconds until the modem has fully rebooted and turn your devices back on.

Needless to say, I get up real early and use Bonus time for all of it. Most of the time it goes pretty fast, at between 25 and 40Mbps. That said, I've been in NJ getting spoiled for the past 2 months. I think Fedora 34 comes out today...

Good thing you don't develop. Xcode updates every time there's a macOS update, and it's now up to 12GB - and sometimes it fails the first time so it has to be re-downoaded - but that's another story. So there's this machine that would need 18GB, right there, and then another 6GB for my wife's machine = 24GB in one morning, and that's not even a game. I used to be able to capture the maOS updates in the system file structure (before macOS deleted it prior to install), copy it to a USB drive, then install it on my wife's computer. But Apple decided that wasn't safe and prevent you from file operations there anymore.

I think what he meant was to just post the link to the summary page on TestMy where your results are listed, instead of copying and pasting them in a post here. Part of the issue is it's hard to read, and if the link is posted the admins can see all the tests run, not just the one sample.

Nothing to fix. The 'limited' thing happens whenever you have anything different from 0% packet loss. In fact a plane going by or a bird circling the area can easily cause 10% packet loss, especially if it's sporadic. You would only see a problem when it goes over 25-30% because of the way redundant forward error checking protocols work. Bottom line: Given the average delay your stats look pretty acceptable. My guess is your speed issue is something else completely, so I would take @maratsade's advice and do some speed tests, if you're not out of data.

It means the servers that run background applications for everyone are overloaded. Background applications are the things that create data, not necessarily what handles what you see at the user level - those would be front-end servers.

Rebooting resets the DNS cache, which sounds like may have been corrupted on the modem as well as the device having trouble downloading. The DNS information propagates across your entire LAN, but may have not yet corrupted the other devices that are working. In this case, you may want to remove power from the modem, then also reboot the device having trouble. Once the device is up, apply power to the modem again. The reson for this process is to prevent re-corrupting the device in question: The device will wait until the modem is restarted and will get a fresh DNS update once it is. However, if the device is restarted before the modem is turned off, it's just going to pull down the same corrupted DNS information.

Plus, you've run Linux before, so using commands in the terminal window should be second nature on a Mini. Virtually anything you can run in Linux, you can rebuild under Darwin (Mac kernel). You can even have a virtual Xserver running if you download XQuartz. And, if you install Homebrew, you can add all sorts of unix/Linux things that have already been rebuilt for Darwin. A good example is Pan, which has always been my newsreader under Linux, and now under Mac.

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.

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.
