If you have some time my experience right now is of one that'll make you cringe.
The problem that starts this novel: I get disconnected from wifi multiple times a day. Sometimes its only the wifi that drops for a few minutes, most of the time it is a total outage. When it's a total outage this is because the gateway reboots itself. At times when the network is very slow and only the wifi drops I cannot get to the routers login page. It never loads or times out. Usually the indicator lights on the gateway are blinking rapidly enough it's almost solid on both bands.
What is it I do when this problem occurs? When it began I would look at the indicator lights and maybe I don't get there in time to see them blacked out, but they're usually blinking rapidly, almost a solid light. The other situation is waiting for the reboot to cycle. Sometimes it would complete the cycle and reboot again!
I can do nothing logged into the gateway thats worthwhile other than check the network status. I don't know how to read the logs so if anything interesting is there I am missing it. I check that the connected devices are of those who live here. I may sometimes power cycle the thing when I can't get the login page to load. I assume the issue is due to overloading. A lot of devices are in the home. So I ignore the issue and when this occurs I just wait it out. Till the first time I experienced this while I was the only one home. I turned off every device and not too long later this happened again. I've debunked overloading with too many devices the cause.
It's out of my control so I see if they have online support because like most computer nerds I'm anti-social. I explain my problem. The comcast support staff I'm talking to asks for my phone number. They tell me they want it because they're going to restart the router, and if I'm not automatically joined back into chat with them afterwards they have to have some way to contact me. After the reboot they tell me "I sent a signal to your router to force a reboot to install firmware updates, your issue should be solved. If you experience anymore problems please let us know!!" Hours later the problem occurs again.
A week or maybe two after this online chat I do it again when I'm so fed up with the problem. The guy asks for the address and account number. If I don't have the account number that's okay! Just the last 4 of the account holders social security number. I don't have that. It's still okay! I just let him know I just live here and are having issues I can't fix myself. The guy collects the account holders name and continues to remotely access the gateway. "Your network isn't setup correctly" I'm told. I knew that was a load of BS. No default passwords or SSID. So what's wrong? I said okay, we'll see what this does. The same day I have the problem again.
Once I was done asking for them to fix the problem I figured the problem is from a faulty gateway. I actually call and ask for a replacement. The same model is sent and what do ya know, my issue creeps up again hours later. I let it go for a few days till I experienced this 3 times in the period of an hour. I call and am not so friendly. I demand the newer upgraded model. I get it and guess what! I still have issues. I debunked the gateway being faulty after using 2 models.
It's a period of maybe 3 weeks before I experience my problem. I thought something just fixed itself maybe a firmware update. Till I hear somebody in the room scream THE FREAKING WIFI ISNT WORKING DO YOU HAVE IT and I get upset. I call comcast after the second time it did this that day. I'm nice this time and explain that I did so much already and I know the problem is not the large amount of devices connected or the hardware. Somebody is sent out to check the junction box. I actually see them checking these boxes very frequently. It's okay I assume because they leave with no repairs done. They call me a day after this and suggest the coax cables may be old. I told them I would run new cable myself, don't send anybody out. The cables changed nothing. I call them again and the last suggestion is that the cables from the pole to the house are old. I dismiss this entirely because that would not cause the gateway to reboot itself or only reboot the wireless. I have given up and tried switching to Verizon but went back.
It's been months with this problem. It's just ignored now when it occurs. It once made me miss out on an opportunity while trading Bitcoin. So in current times I am curious about cyber security. I had a port scan done and found 7547 open. A google search tells me this Port is associated with application layer protocol for remote management of end-use devices. Further research pulls up articles upon articles about 7547 exploits found November of 2016. Frequent reboots and inability to load the web interface are symptoms of this infection.
The reason Comcast support is an absolute joke and will waste your time is because they show me how they have zero technical skills outside of the script they're told to follow. There is zero true investigative skills. Every time I contact them I have to call the shots or I'll just get a reboot from them, told to reset the gateway, or sent a replacement device. Never did any of them have any skills to think outside the box to think of what might be the problem. I just minutes ago chat with support and asked for the contact info for whatever they call the security department I asked if she could even look up the latest firmware version. She gave me steps on how to do it after getting my model number. The directions were wrong. She told me to google how to update firmware than said I could upgrade my gateway. Comcast automatically delivers updates and there is no update checker or things like that for the model I have.
I started calling when I had this problem just to see what they would do. It's really pathetic. You get stuck going in circles with them. Never was my problem escalated to somebody with better skills. It's as if hacking is non-existent to them. Now I know the blame may not be on them. They may not be getting troubleshoot guides for anything thats not a common issue. They should, be a little more knowledgeable enough. Maybe enough to assume its a problem because of someones malicious BS.
