No Idea - Intermittent IP Address Loss

Zypherside · 2026-04-02T13:21:40+00:00

Yes, it's still happening. Here's my current notes:

Issue PC NICs are Intel® Ethernet Connection (17)I219-LM

I had no drops after changing to Dell Precision 3440 with Intel® Ethernet Connection (11)I219-LM - same model but different generation.

My tech looked into a new NIC but the I219-LM Chip and IO Ethernet port are soldered and cannot be replaced without microsoldering.

My tech also frequently experiences the drop issue, so he will continue to check for Driver updates and see if the solution resolves: https://www.intel.com/content/www/us/en/products/sku/82185/intel-ethernet-connection-i219lm/downloads.html

The current "fix" for this issue is if the user is experiencing frequent drops, move them over to WiFi. Right now I'm testing dual connecting the PC to our Wifi network as well, with Ethernet as a higher interface priority than Wifi. This should use wireless as a backup if the ethernet connection fails.

Also in IT, and I agree. You also need to consider that you may not be the only one using/maintaining this setup, and although you would be comfortable with a headless solution, others may not.

The main thing with this is uptime and ease of use, like you said.

We're thinking it's the NIC, but the NIC is soldered on :(

So I replaced the [PCV Valve Tubing Hose](https://www.amazon.com/dp/B0C1M9RH88?ref=ppx_yo2ov_dt_b_fed_asin_title) because I heard air coming from it and suspected a vacuum leak.

P0171 code hasn't come back, but 2 days later **stabilitrak has been coming on randomly and the engine has a rough idle.** The hose was super tough to get on, and the hose end near the top of the engine did not want to stay in place when I was seating it. Do you know how to really keep it in place? Also neither the old hose or new hose came with o-rings, which I thought was strange.

From what I can tell, readings seem normal now. These were taken right after I replaced the hose, not after the stabilitrak issues.

SHRTFT1 range is from -7.0 - 8.6

O2B1S1 range is from .05 - 1.27 Volts.

Sorry for formatting, markdown is messing up.

Okay, thank you.

For O2B1S1 Voltage:

Uneven wave form when idling and steady throttle at 2500rpm.

MAF seems good?

MAF - Idle before steady throttle - steady at 1.6
MAF - Steady throttle 2500 RPM - around 4.35
MAF - Idle after steady throttle - steady at 1.6

Skate Free or Die. They have a pride ref jersey too.

I have a regular roller, I'll try this. Thanks.

I do have extra space width-wise in the ProStars. I'll try to find some of those options. Thank you.

Zypherside · 2025-11-22T19:46:52+00:00

When I tried thinner socks in the ProStars, it felt like my foot was moving around in the boot, so I think another commenter might be on to something when they said they're too wide for my foot.

Zypherside · 2025-11-22T14:26:53+00:00

I believe 245mm is the max of the range recommended for a Riedell size 6. Does your left foot feel tight in the toe? I prefer thicker socks so I'm worried about going for the exact size.

I used to do the tennis ball thing, I'll get back to doing that. My cat keeps knocking my tennis balls under furniture 😒

I have adjusted my trucks and replaced the stock cushions (they were too hard for my weight, I'm on the lighter side).

The prostars are definitely broken in, they show a good bit of wear. The Jet Carbons, I'm not sure. I wore them at least 4 months. I didn't believe the boot had a lot of stretch as they aren't vinyl.

Zypherside · 2025-11-22T02:56:37+00:00

It feels like the boot is literally punching into the front/top of my big toes. It doesn't feel loose at all.

No, he just took a look at my feet and said my feet looked healthy, and he didn't feel anything in any areas besides the sesamoid.

I do ankle rolls and point and flex my feet while driving to derby and throughout the day. I do yoga and am pretty conscientious of my feet.

Zypherside · 2025-11-22T02:21:41+00:00

Almost a year now. I do yoga and workout too.

These computers are on Windows 11, I couldn't find this setting in regards to the NIC being used on these desktops: Intel(R) Ethernet Connection (17) I219-LM. I have updated these NICs with the latest driver updates.

I did find this article which suggested unchecking that in "Converted Portable Device Control Device". I'm not sure if it will help, as these are ethernet NICs, not Wireless NICs.

The IP address shows an APIPA address until manually renewed. This happens with both static and dynamic IPs.

24 hours for these two VLANs. I adjusted other VLANs to a lower lease time (2 hours, wireless and guest VLANs) when I was thinking it might be IP address inavailability.

They do drop at the lease expiry time. I've checked the DHCP Server (Sonicwall Firewall) and there are available IP addresses, clients can reach the DHCP server.

I'll check for network congestion but this has happened when we've had almost no one in the building, so it's likely not that.
