When we're using wifi for skype/zoom meetings from my spare room/office the screen freezes, signal drops etc and we've been advised to get an ethernet connection. So I'm planning to run an ethernet cable from my virginmedia superhub to the spare room. To do this I'll have to go through the wall, run the cable along and up the outside wall and then back into the spare room from the outside wall. It's a run of about 5m. To do this the cable will need to make 4 right angle turns. The cable easily bends this much but will this reduce the performance - it's a CAT 7 - thought I might as well future proof a little! Thanks
Are 90 degree turns in ethernet cable ok?

Do’s & Don'ts of Cat5e & Cat6 Cable Installation
Don’t
1. Bend the cable more than at a 90 degree angle
2. Exceed the minimum bend radius for a 4 pair cable which is 1 inch.
3. Use more than 25lbs. maximum pulling tension on a 4 pair cable
4. Over tighten cable ties on cable bundles.
5. Run hand trucks over the cable
Do
1. Install telecom. cables at least 5 inches from Power Lines
2. Use loose Velcro to bind cable groups where possible
3. Avoid unnecessary bends in the cable runs
4. Make computer room connections with labeled patch panels
5. Maintain 568A or 568B color coding for the entire system

Thanks Bernard - so 90 degrees seems ok. Does the fact that its cat 7 make any difference? As I understand it a bend radius of 1 inch means its coming back on itself which it definitely wouldnt do.

Drip loops
1 inch for most un-shielded Cat 5 cables.
Too be certain check the data sheet for the type of cable you are using.
CAT6 and CAT7 are very intolerant of tight bends. But CAT5 performance will be fine for your purposes so if you rag the CAT7 in it'll probably work up to 1000Mb/sec which is plenty for video conferencing, just don't pinch the corners tight.
