Just arrived and display won't power on

U.FL-LP-040 and U.FL-LP-066 both mate to the same U.FL-R-SMT receptacle. 2mm diameter. It’s only the attached coax that is different.

That isn’t frameworks that’s normal. I’ve worked on two recent dells that friends have, and have the exact same design. The design is so that the cables don’t come off in your traditional manhandling of a laptop. And I feel for you in regards to having issues but realistically it’s not that hard if you just slow down and take your time. Just make sure to route the cables so that they’re at an angle that doesn’t force them upwards that’ll cause the connectors to detach.


These are both U.FL connectors. Are they the same? There is a third one between the two that I dealt with very recently when I got the wrong cables, but I don’t know where they are at the moment.

EDIT: What I meant was there was at least one other size between the two, and all have been called U.FL connectors, just the standards have gotten smaller over time. This is essentially the two extremes. Everything about the connectors and the plugs is essentially the same except the size. This creates confusion and I was simply providing some information to help in case people do get confused because things look a bit different.

They are not both U.FL. Again, there are a number of connectors of the same general shape but in different sizes. Hirose defines U.FL as having a 2mm diameter receptacle. There are seller that will mislabel things.

The larger one is from a wifi card around 17 years old, I have been working on this stuff since well before then, and those connectors were always called U.FL at that time, just like they are now.

If you heard different sizes called U.FL, that was just wrong. Other sizes are different series, like W.FL, E.FL, etc. Hirose has a ton. And each has a defined receptacle size. They do have the same general appearance, but that doesn’t make them all U.FL.

But more on topic, when Framework lists their cables a U.FL, I trust they are either actual Hirose U.FL or a fully compatible connector, which Hirose does define as using a 2mm in diameter receptacle.

Like I said the connectors on wifi cards since they were first created have always been called U.FL. I can’t find any sources that state this, but every place that I look says that U.FL was invented in 1991 and was used in laptops including for miniPCI wifi cards which is exactly what the larger card is and working with hundreds of laptops, and researching hundreds more wifi cards at the time I never saw a miniPCI wifi card with a different connector. You can belive me or not, but I was around and in the industry when wifi was first created and I know what literally everyone called the connectors.

If it is not U.FL, then what are those larger ones? It was the only standard used for miniPCI wifi cards, and was used internally on most routers at the time, pretty much 802.11a through at least 802.11n almost exclusively used those for the board connectors unless the antennas were soldered.

I don’t think there is much progress to be made in continuing. And we are also filling someone else’s thread will this back and forth.

The general U.FL series datasheet, and the datasheets for all the separate parts within the series define the size. If you don’t believe it, or if you think Hirose has changed the definition of U.FL, you can ask them.

I don’t need to ask them because I already know the answer. I was simply trying provide some information that might help people in the situation (very likely) that their card/connectors look different and I was clarifying that it works the same even if it looks a bit different which is true whether the other connectors are called U.FL or not, whether they are compatible or not.

That smaller board uses an mhf4 connector, all i had to do was read the labeling on your cards and google them to find that out, you know google is free right? For info, any connector that is that shape is colloquially called U.FL STYLE, not U.FL, but styled after U.Fl thays probably what you were seeing and mistaking as it being identified as U.Fl

Let’s get back on topic please. And personal attack posts have been hidden.

Finally managed to get the WiFi antenna connected to the replacement module.

Onward! to the next circle of hell…

This worked for me, removing the second memory stick.
