Calling computer network specialists

Recommended Posts

I deal with stupid network issues at work, I don't wish to do the same at home.

Perfect example... two weeks ago a device that had been communicating with no issues stopped communicating. The resolution... set the speed from auto-detect to 100mbps full duplex. Worked fine for the rest of the week, then sat idle for two weeks, as I was on vaca, then working with different devices. Today, no comms again. Set it back to auto-detect and it communicates again.

Bad news,  wasted hours on it three weeks ago. "Good" news, it only cost me 5-10 mins today mostly from the reboot time.

And I'm not officially an IT guy, but we have to handle out own network in our training center, luckily I have a coworker more knowledgeable that I on networks.

I can tell you why it's happening.   Starts with a T ends with rendnet.

Seriously, only buy that brand for stuff that really doesn't matter much.  Their powerline lan adapters work fine.  No where near their advertised rate, but they work.

Their NICs will reliably work at 100mbit.  I wouldn't buy a gigabit card though.

Low end switches where you aren't really stressing it?  Fine.   Their POE switches have been fine, but even with a ton of traffic, cameras aren't really pushing that much data.  As long as it's not your main switch at a 32CAM NVR, it'll be fine.

As a router?  No way.   Too much to go wrong.

Insane speed increases too.

Wi-fi, same devices, same location, roughly the same time of day and same other network traffic. Using speedtest.net, results went from ~40 down & ~60 up to low-to-mid 200s down & low 100s up. Considering I'm on a 200/200 FiOS plan, I'm very pleased with those numbers on Wi-fi.

Can't get OpenVPN to connect yet, must be missing something. Will need to play with it more later.

While I'm at it.... any Raspberry Pi gurus here?

My Florida house has Xfinity, 100mbit plan.

I consistently get 120ish down.   I believe they overshoot the rated limit on your plan to account for all the shitty routers out there.

Think of it...every dumbass that buys a $29 router is going to call and complain that they only get 86mbit on a 100mbit plan so they just tweak the modems up to account for shit end user gear.   Dumbass now gets 101mbit and thinks he's got one up on the cable company.  Smartguy with a good Asus router gets 20% more than that.

Xfinity would never do that.  Are you kidding. They’d say that you have to rent their modem/router combo box to get advertised speeds. 
 

On the router side I’ve Used Xfinity’s box and also had various Netgear/ASUS types and always had bad areas of the house. Went with an Eero 3pack when they were on sale and it’s night and day.  Light on the configuration options but works really well.

Not kidding.  It's been my experience.  Since I'm the young techy whipper snapper around down in the Villages, I've replaced a handful of routers for people.   Every person went above their plan with the new router.   I take my Surface pro, plug in a wire to see what it looks like then walk around on WiFi.  Big difference.  Shrug.  Maybe the Xfinity in central FL is run differently.

I guess maybe. Just seems counter to the standard Xfinity behavior toward their customers.  I just looked and from the router itself I’m routinely getting 360 on a 350 plan. That’s with my own router and modem.  It could be that they do it to compensate for congestion on the head-end. From what I remember that is susceptible to congestion from neighbors/etc all using the same frequency range between the modems.  I doubt it’s to make 3rd party routers look better when Xfinity makes money renting a competing product.

All newly connected network gear seems fast..... Until the routing tables fill up and/or become corrupted, or a minor bug finally manifests and corrupts the firmware or configuration.  If your firewall has a white/black list, that fills up too.

Anyone who has connected a sniffer to a public IP has seen the daily assault of hacking probes routers endure on a daily basis.  Hundreds, sometimes thousands of port probes and attacks a day.  Even if they all get blocked, that can f-up a router over time too.

With that said, newer routers can handle more bandwidth per channel/port and manage traffic a little better.
