windows 7 – PC internet connection goes offline intermittently, but always comes back online when I turn on my cell phone

Intermittently, my internet connection will terminate (I get the yellow exclamation point icon in my system tray). When this happens, I can consistently bring it back online every time by turning on my Galaxy S6 phone. It’s been doing this for a few years and I am just now getting around to asking about it.

About my system

  • Windows 7 (come at me)
  • PC connects directly to cable modem
  • Phone connects to wifi
  • I use syncthing to sync between phone and PC. First thought is to uninstall syncthing, but the issue is very intermittent and might not occur for several days on end

Anyone ever heard of such a thing?

emails – SMTP messages are failing intermittently

Inherited a Drupal 7 site running Open Atrium and the sending of email messages is failing intermittently. 1 out of every 10 emails fails the with unable-to-authenticate error message. How are most emails working then?

Site is running on Pantheon and hasn’t been updated in over a year.

Google Cloud Classic VPN disconnects intermittently

A couple of weeks back we have created google cloud classic VPN and created a tunnel with other on-premise network the connection was established successfully and we are able to access their application(s) but after a couple of hours, VPN started disconnects intermittently. I have observed establishing IKE_SA failed, peer not responding error in the logs.

When VPN goes down the VPN tunnel status was sometimes NO INCOMING PACKETS and sometimes FIRST HANDSHAKE
I don’t know what is happening.

Below is the VPN configuration details:
Region: us-east1
Routing type: Policy-based
IKE version: IKEv2

Can someone explain what’s going on?

formulas – Import XML intermittently doesnt work but sometimes does (currencies/shares etc)

I have a spreadsheet monitoring my Stocks and cryptos etc.

I have a formula which 50% works and auto updates and 50% doesnt work and comes up with ‘N/A : Could not fetch URL’…when multiple others are working and that one also sometimes works.

The formula is;

=SUBSTITUTE(IMPORTXML(“https://coinmarketcap.com/currencies/”&A4,”//div(@class=’priceValue___11gHJ’)”), “$”, )*GOOGLEFINANCE(“CURRENCY:USDGBP”)

A4 is the title box next to it so its pulling into the box in this case ‘Ripple’.

Can someone guide me or help me find a substitute website for crytpo prices which works (im saying this guessing it could be a bot blocker from the URL itself randomly?)

Sharepoint 2016 not able to connect to database intermittently

I have a Sharepoint 2016 Farm configured with Shared Roles. Below is the Configuration details.

  • 2 X Web Front End Servers with Distributed Cache
  • 2 X Application Servers with Search
  • 1 X Domain Controller
  • 2 X SQL Servers in Failver Cluster (configured with High
    Availability)

Although I am facing an issue wherein One of the Web Front End Server (WFE1) is sometimes not able to connect to database. I see the logs and find the below Error message.

Unknown SQL Exception 53 occurred. Additional error information from SQL Server is included below.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)

This issue happens twice in a day. How do I figure out what is happening wrong. Any support will be highly appreciated.

MacOS Intermittently drops 5Ghz Wifi Connection

I know there is a plethora of questions pertaining to MacOS and Wifi Connections dropping, but hear me out.

I’m running:

  • Machine: Macbook 16" i7 Big Sur 11.2
  • AP: Unifi AC Mesh (Running both 2.4Ghz and 5Ghz (SSID: Rootman-Home)
  • Router: Unifi Security Gateway
  • Bluetooth Headset: Sony WH-1000XM3

Ever since I got my Macbook my 5Ghz home Wifi has been dropping at really odd times, sometimes once every other hour, sometimes once every other day. When it drops I’m unable to reconnect to the same SSID for 5Ghz for at least about 2 – 4 minutes, I’m able to instantly join the 2.4Ghz channels no problem.

One time, I noticed as I pulled my wireless headset from it’s charging cable (it was charing from the Macbook via a dongle) my wifi just dropped. Today, my headset was connected via Bluetooth and when the Wifi dropped again, I tried reconnecting and same issue, I switched my Bluetooth headset off and it reconnected instantly.

Went through the logs and found this (this happened at the time of the Wifi disconnecting):

I’m new to MacOS, but what it looks like to me is somehow it’s trying to query information from the headset, it’s not working, this then causes some kind of event where MacOS decides to review/reconnect to currently connected devices, this leads it to kick off the 5Ghz SSID (maybe some kind of bug) and temporarily black list it. After it sorts out the Bluetooth connection to my headset, it then re-allows a review of blacklisted devices and lets me back in to my 5Ghz.

Some solutions suggested I disable Wake on Lan (Or Wake on Wifi), I’ve done this, and I’m gonna give it a few days and see if this fixes the issue.

Other solutions I’ve tried:

  1. Restarting my Macbook.
  2. Reconfiguring and resetting my network.
  3. Disabling Bluetooth and re-pairing BT devices.
  4. Formatting / Re-installing MacOS (I did this a few months ago).

I really don’t wanna take this machine in to be repaired, I don’t want to sit without a work station for a couple of days so I’d rather sort the issue out myself.

I would really appreciate if someone can help me make sense of these logs.

keyboard – Late 2011 Macbook Pro 13″ FGHJKL Keys Intermittently Working

My MacBook Pro, a late 2011 model running High Sierra has been giving me this issue where some keys – FGHJKL, aren’t working sporadically. Sometimes it works fine for a while but then after some time now it starts to behave more sporadic until it works none at all.

I’ve read a lot of posts on this issue, but none offered any real help. Some say it could be that since the battery is swollen (which it is) then that could be the root cause, so I let it run without the battery and it didn’t work fine without. Some say it could be a software issue, so I went ahead to resetting the SMC, PRAM, reinstalling the OS, clearing junk cache, and even clearing out some .plist files from the Library > Preferences folder.

My only remedy is to restart the computer where it works fine for a while. I’m also using karabiner to map combinations to the keys that don’t work.

I’ve been having this problem from late December up until now. However, it’s not the first time.
Last year around this time I had the same issue with it and I had to buy a new keyboard, but even so, the issue persisted. As time went by it went away until now. I’m not sure if Apple is screwing with my computer ( I’m getting pop-ups telling me I should upgrade the OS ) or this issue is legitimately either a software or hardware issue. I would like to know what I’m experiencing so I can act decisively. Any help is appreciated thanks.

35mm – The film in my film camera won’t rewind. 31 frame flashes intermittently

I’m new to film photography. I recently tried to use the old film camera I had lying around the house, a Kodak S1100 Xl. I shot 31 pictures but couldn’t proceed to shoot more as the LCD display showed the 31 frame flashing intermittently and it wouldn’t let me shoot more. I bought a new battery and tried to shoot more pictures/rewind the film but it won’t work. I read the manual and found out that there’s a manual way to rewind the film, a small “R” button, but that that didn’t work either. I figured the film wasn’t loaded correctly in the first place and that’s why I lost those 5 pictures. Now my problem is that I can’t rewind the film that is supposed to rewind itself automatically after the last shot. I have to add that the number 31 stops flashing when I press the manual rewind button but won’t count down from it to release the film.
Any help?
Should I take the film out in a dark room at night and rewind it myself?

macos – Mac OS, mouse right click intermittently stops working

I am using Mac OS X 10.15.4, and intermittently my mouse right click starts behaving like a mouse left click; i.e. no matter how I configure my mouse, I cannot get the right click (secondary button) behaviour. It is an Apple USB non-cordless mouse; the Mac came with a cordless mouse but that died.

It usually comes good after unplugging and replugging the mouse from the USB port, a few times.

It is possibly a hardware issue, but if it is, why does right-clicking do anything at all?

Probably the only “uncommon” way I use my Mac is I leave the emacs editor constantly running; emacs is a huge program and I guess there is a chance it is doing something strange.

Is this a known issue? Or does it sound like a hardware issue?

active directory – Domain-Based DFS Working Intermittently

I have DFS setup on my network as follows:

  • A domain we’ll call DOMAIN.LAN.
  • Two AD controllers, let’s call them DC01 and DC02.
  • Two file servers, let’s call them FS01 and FS02.
  • A Windows 10 Pro workstation joined to the domain.

On the file servers, I have a share called “public”, which is successfully accessible from the Windows 10 workstation as \FS01public and \FS02public.

On the AD controllers, I have a DFS namespace set up called “dfs”, with a share called “public”. This share has the following targets:

  • \FS01.DOMAIN.LANpublic
  • \FS02.DOMAIN.LANpublic

I’ve tried accessing the share from the Windows 10 workstation in the following ways:

  • \FS01public: This works 100% of the time.
  • \FS02public: This works 100% of the time.
  • \DC01.DOMAIN.LANdfspublic: This works 100% of the time.
  • \DC02.DOMAIN.LANdfspublic: This works 100% of the time.
  • \DOMAIN.LANdfspublic: This works intermittently.

It’s this last one that’s the issue. When I say “intermittently”, I don’t mean that I click on it once and it works, then click on it again and it might not. I mean that it may work for several hours, then stop working for several hours, then with seemingly no changes start working again.

I’ve tried changing the targets from the FQDN of FS01.DOMAIN.LAN to just FS01, or even just the IP address of the file server, and this makes no difference. However, since I can access the share through the DFS name space if I hit the AD controller directly rather than the domain name, this would seem to rule out both DFS configuration problems as well as DNS problems (even though the fact that it’s intermittent would also seem to point toward DNS), which is why I’m unsure on how to proceed with troubleshooting.

A couple of things to note that may or may not be relevant:

  • DC01 is running Windows Server 2019.
  • DC02 is running Samba 4.9.5.
  • FS01 and FS02 are running Samba 4.9.5 and are domain member servers.
  • The Windows 10 workstation is connected to the network with the servers over a VPN. However, the IPs of DC01 and DC02 are (for testing purposes) hard-coded into the workstation to make sure that it can resolve DNS properly. Pinging all of the above FQDNs works as expected 100% of the time.

I do recognize that the VPN could be an issue. However, a workstation that is also local to the servers exhibits the same symptoms, so I don’t see the VPN as a differentiator. The VPN connection to the server is solid as are both internet connections, and ping times across the VPN are 20ms or less.

I’m looking for either someone that has experienced this issue and has the solution, or at least a process I can use to further troubleshoot.
